Groovy vs JavaScript: What are the differences?

Groovy and JavaScript are two popular programming languages. Let's explore the key differences between them.

  1. Syntax: Groovy has a more simplified and concise syntax, inspired by languages like Python and Ruby. On the other hand, JavaScript has a more complex syntax, with its own set of rules and conventions.

  2. Type System: Groovy is a statically typed language, which means that variables have a specific type that is checked at compile-time. JavaScript, on the other hand, is a dynamically typed language, allowing variables to change their type during runtime.

  3. Object-oriented Programming: Groovy is built on top of Java and supports object-oriented programming (OOP) concepts such as classes, inheritance, and interfaces. JavaScript, on the other hand, is a prototype-based language, where objects can be created from other objects.

  4. Functional Programming: While Groovy supports functional programming paradigms, it is more oriented towards object-oriented programming. JavaScript, on the other hand, has strong support for functional programming, with features like anonymous functions and higher-order functions.

  5. Interoperability: Groovy has excellent interoperability with Java, allowing developers to seamlessly integrate Groovy and Java code. JavaScript, on the other hand, is mainly used in web browsers and has built-in support for manipulating HTML elements and handling events.

  6. Community and Ecosystem: JavaScript has a larger community and a more extensive ecosystem compared to Groovy. There are various libraries, frameworks, and tools available for JavaScript development, making it a popular choice for web development. Groovy, although widely used in the Java ecosystem, has a relatively smaller community.

In summary, Groovy, ideal for JVM environments, boasts concise syntax and seamless Java integration, while JavaScript, widely used for web development, offers flexibility and a vast ecosystem of frameworks.

Please Help in creating a test framework

Hello Devs,

I am planning to implement a ETL test system for checking data quality and business use cases. I am confused on what stack to use. Any advice on the below will be very helpful.

  1. Any existing frameworks and its source code for help
  2. Any other stack apart from the mentioned stack (that might be suitable)
  3. Any ideas for features are welcomed.
  4. The usage of multiple BE stacks.

If you want to create using Python language, Robot Framework is one very helpful tool to improve your test scripting and we have a lot of methods created by the community. If you want to use Javascript, Cypress in terms of benefits is the better option to create and maintain tests, and run and generate reports in many browsers is really easy with them.

Hi Syed, I wish you all the best. I'm an experienced programmer with more than 15 years of experience. Recently in my company, we were trying to hire a MERN Full-Stack developer and we found many who can code in React but few who were capable of thinking logically and actually able to solve the business problem. Learn any language or package, but keep in mind to learn for a goal. Syntaxes don't matter, we hire to achieve goals. Small to medium companies, usually hire full-stack developers due to the lack of resources. So it would be great to learn the following: For Web, I would suggest "React", and for mobile development, "Flutter" comes in handy with lots of promising future. How about learning both? much better but it's all about you. Good luck!

Hey everyone, I have a matrix chart drawn in HTML5/CSS 3 dominantly using CSS grid. I would like to add interactive features and am unsure about the best tool. My programming knowledge is limited to 2 semesters of Java in college, so I'd have to learn the language as I go. I am open to anything, but the selected languages would be useful in future projects.

Here are the features I am attempting to add to the site linked as my blog:

  • Assign over 120 attributes each to over 400 elements (probably in a DB)

  • Procedurally position elements in a matrix chart based on user-inputted filters (filtering and searching)

  • Procedurally position matrix elements based on attributes weighted by user-input

  • Change style of elements based on user input (highlighting)

  • Allow saving matrix chart states to be revisited or shared

  • Provide a user-friendly interface for users to submit the above input

  • Build several columns or matrices that are separate but related and seamless to the viewer

PyCharm + Python + Flask + Jinja2 is enough to build web server/ajax and JavaScript + JQuery (maybe React). You can write small easy application but also extreme high scalable application.

I know Java but it need 4x time more code and code is not clear (too much forced use of @decorators) - too complex and takes more memory :)

Remember if you code in Python it is easy to code in Java but if you code in Java you must understand that Python is much more flexible and powerful - also easier to learn.

There are two main facets to interactivity - whether your frontend (Javacsript, HTML, CSS) is programmed to behave dynamically based on events and on any other preprogrammed behavior, and based on what information your server can send and receive and compute for the benefit of your frontend. For the former (a dynamic frontend) you'll need to use Javascript (or Typescript) in some form. For the latter (a server with custom behavior and data endpoints beyond just sending static HTML etc. files), any of the major languages can serve this purpose. However, if you are going to create a dynamic frontend with Javascript and don't know that language at all, then learning it will be a task in itself, and without knowing a backend language well either (probably the case with only two semesters of one language a while back), you ideally don't want to also have to learn a whole other backend language on top of that. That's where NodeJS comes in. It has essentially the same exact syntax as frontend Javascript (just different native libraries). Since you already need to learn Javascript to make the frontend behave dynamically, if you also want a custom backend, NodeJS will spare you a big learning curve on top of the existing learning curve of learning JS. NodeJS is also highly performant for low-compute high-volume requests, i.e. handling a large barrage of requests if each doesn't require a lot of complicated behavior on the backend. A lot of coding bootcamps teach this, commonly called "full stack JS", for this reason - it allows someone to learn a constellation of full stack web development skills from the mastery of one language syntax. NodeJS + ExpressJS is also one of the easiest backend languages + REST API library to use to build a backend. Look up "NodeJS Express Hello World", and you'll be shocked at how easy it is to build a basic server. As far as frontend frameworks go, if this project is very limited in scope, JQuery could be fine, but I'd highly recommend learning React for something more involved - it will be immensely easier to manage and maintain, and generally lends itself to much better and more intuitive code organization. Its use of components will also be somewhat familiar and intuitive from the object oriented programming you learned through Java. Create React App is great tool to use, especially when first learning React, to avoid all of the finicky nonsense in configuring transpilation etc.

React is hands-down the tool I recommend to add interactivity to your matrix. Because it is Javascript, it will leverage a lot of the formatting from Java. Python would be very foreign to you. React shines in allowing you to use OOP principles within the JavaScript language and it is really powerful, fast and browser friendly.

I am unhappy. When doing my research, I heard Python is useless. Data science is an unworthy field thanks to TensorFlow, and web scraping has also become pointless since the introduction of the PWA. Since PWAs are only frontend, I feel forced to learn JavaScript, and to ditch Python. I love Python with all my mind, it's simplicity, conciseness, and easiness as a tool. Here are a few questions:

  1. Should I forget Python and move on?
  2. Are there any PWA alternatives to JavaScript/TypeScript. I've been thinking of using Python for WASM and use HTML+CSS for the DOM to create the PWA. Is this possible?
  3. Why is JavaScript such a pain in the butt
  4. What's the point of me learning Python if it's not useful for web development?

You should not ditch or forget Python because of what you hear or because of one particular project. It's probably going to stay relevant and useful for the coming 20 years. If you're a programmer, you should however be prepared to use several tools, and programming languages are just part of the toolbox (like HTML or CSS, but also your IDE, powershell, linux commands, etc.) It's not for nothing that this site is called "stackshare".

JavaScript is reduced Python. Python is powerful. If Python is not powerful you can mix it with C/C++ - this is not available in JavaScript in easy way.

Python is definitely not useless, It has a ton of usecases, with a huge community behind it, but not that performant and consumes lots of resources, I don't think you should abandon it, and PWA is kind a in its early stage, so I doubt that there will be any language better than js for developing it any time soon, so I guess there are no alternatives, but I guess you will like js/ts if you spend a little more time playing with it, and the same goes for wasm it is also in its early stage, and i guess web assembly and rust will be used a lot for that, and lets say you have built a frontend web app , now with the help of python + django or flask you can write server code, and learn a little bit about databases, then bravo you are a full stack dev.

Whatever you do don't go WordPress path. Developers over-there tend to ignore system limitations and hardcode and overengineer their solutions so as to please their clients. If you are a beginner probably you'll get to work on someone else's shitty code and will be asked by your boss to do "yet another impossible thing with Wordpress". And... Probably... You'll do it.

My suggestion is: think in stacks and don't start too low. Starting with HTML, CSS3 and JavaScript is too low. Start on higher levels and with something practical. You'll have time for basics some time later and it would be much easier, because you'll see those technologies are compliment to what you do and not your main objective.

My suggestion for you:

  • Android Mobile App Development path (complex enough so you won't get bored)
  • All things web3 crypto, nft, virtual reality, blockchain path (has tons of computing web development tasks)
  • Cloud computing setup and administration path (good, because you say you're not good at programming)
  • Artificial intelligence and automation (this is future, people need this)

I've also found it helpful to think of each stack as a surface (find Google Images "radar chart") . Every time you try to learn something new you start in the center, with all technology-points overlapping. You are as low as you can get and you know nothing. Your job is to expand outwards each technology so as to make a stack-surace. The more surface the better. You'll see that some technological-aspects are easier to expand than others and plan your time accordingly.

Have a good start!

You can also try starting with one of the big marketing agencies. Even if you don't feel like you're ready to start as a web developer (you likely are, though, they hire at all levels) you can start as a content author or similar supporting role until you're more comfortable, then transition into a development role within the same company when you're ready.

I don't believe that you are confident about your decision to follow a career path as a developer. This migh be your department's fault and not necessarily yours. Most good developers are already working as developers at that age. Although your current status states that you are an intern you are struggling to find a good starting point. Since you are interested in website developmnet you can start learning programming using a mainstream CMS such as wordpress. Do you know how many companies and self employed guys make their living by customizing wordpess? But if you want to step out of the crowd then seek for junior jobs on a fintech or on a vertical market such as travel or betting. Search for online job oportunities and find out what technologies these guys use then take an online course and start learning the language. Within a month or two apply for a job as a junior and use as reference the online course.

JavaScript is an ever growing technology with lots of opportunities and great depth for both front end and back end development. I would say that JavaScript is a safe bet in terms of furthering your career as a developer in 2022 and beyond. There’s lots of tools and frameworks based on this language that you would have to make decisions on which ones you want to become an expert. I recommend you follow interesting people that you admire to draw inspiration from. Such as Ben Awad or Jeff Delaney.

Just don't .NET. It was a failed idea from the start. Node and javascript are easier to learn, with much wider adoption, and more active communities.

.NET is an old experiment in using a markup language to separate the UI from the business logic. The idea was that this would allow a small team of hyper-competent engineers to build the tooling and code for a large team of less-skilled front-end developers to leverage. In practice, leveraging that customized UI markup requires understanding and adjusting the underlying code. The result is that any UI change requires a hyper-competent .NET engineer.

However, many larger companies bought into it a long time ago, and now have a hard dependency on old monolithic .NET ecosystems, and they do need .NET developers to maintain them.

So, you can get a well paying .NET job without much difficulty. However, you'll neither like it, nor be doing anything interesting. There's no growth here, only a very long slow death of .NET (that'll probably take another 20 years).

Node and Javascript are sticking around, and still growing.

There is not too much you can learn just from the tutorials, there are other important factors that you need to be a good programmer, you need to communicate, and do projects according to the liking of the client/project manager.

I think with anything related to personal development is about comfort zone management. Being too comfortable one can feel bored, too outside ones comfort zone one may feel out of their depth. I'm sure there's more to this down the rabbit hole of psychology. However I found learning about motivation and striking the right balance of extending myself has truly helped keep me pushing forward at a steady pace. In the end do projects that are motivate you whilst incorporating learning as you go. So pick a project that you know is possible, that you can achieve if you put the work and effort in, and that the outcome of it will be as you expect. I think even the perfectionist in you will find that satisfying.

Start with building a solid understanding of computer science fundamentals. Understand the basics of building blocks - memory, processing, storage, networking. Understand what CPU bound, memory bound, I/O bound, network bound processes are. Understand the cost of accessing data from Memory vs. Disk vs Network. Understand how multiple CPU threads help in optimizing the performance of a single machine.

Build expertise on a programming language. You may pick any language of your choice. I would recommend starting with Java / Python. Make sure you know one language really well. Build a strong understanding of Data Structures and Algorithms. You should be able to develop an intuition on when to use what. You may practice DS and Algorithm problems, using the language of your choice, on a competitive coding platform (e.g. Leetcode) or by building your own App!

Next, get familiar with basic cloud computing and distributed system concepts. Here is a good resource for that - https://www.youtube.com/watch?v=p7NkTUyEE1o&ab_channel=JeffreyRichter If you understand the computer science fundamentals well, you will be able to apply those concepts here as well.

Most employers don't expect from you to know how to implement CI/CD or any other funcy stuff. As junior developer you should focus on building a good toolset of good software practices & principles. Your soft skills are important as well. Learn about soft skills. Be eager to learn, be humble and show you talent and your creativity through your work. If you want to become a good developer ( at first) and a star engineer (at a later stage) then computer programming (coding) is your number one priority . Coding is like painting. Putting aside your talent, you have to practice a lot and improve your outcome each time. As junior developer you can learn how to write good code by studying existing code found in public git repositories (i e , github). As junior developer you should study some good software principles (i.e., DRY, KISS, YAGNI) and always recall them each time you write software code. As junior developer you should learn about coding standards and conventions. You will have to follow to your company's coding conventions (soon or later) as well as you will realize that you have to write code cosistent to the existing code base. At the end of the day, code consistency matters a lot. You have to improve your code day by day. If you manage to follow some good software practices you will find out that you will need an ORM to work with your database. Then you will realize that you need the X web framework to build your REST API etc. To sum up, you will start building a toolset with a single programming language and some good software practices & principles and then you will put new tools in it day-by-day.

Although Lua is a very simple,efficient, elegant and welcoming language, Python is extremely versatile. Therefore, if you want to get into programming without a defined direction, Python is the way to go. It has a lot of libraries, the ability to do anything and it is closer to other languages than Lua is (yeah I know about Lua and C, but from a learner's point of view, it makes sense). Additionally, Python will be a marketable skill, but I for one have not yet seen job offers for Lua devs.

Python will be used in order to train machine learning models from our data. We chose python for this task because it is the most common language for machine learning. It has very performant libraries like numpy and scikit-learn that provide functionality for manipulating data and creating models that you cannot get in other languages like JavaScript and Java. Additionally, it is the most familiar language for us to use for machine learning because almost every machine learning course teaches ml using python.

Javascript will be used for both our frontend and backend on the web service. JavaScript is ubiquitous as the language to use for the frontend. For the backend, we decided to create our server using JavaScript because of its easy setup; using Express we can create a server in just a few short lines of code. It is simple not only to run the server locally, but to host it as well because any major service will support the language. JavaScript is a simple language to code in and familiar among our team members, so using it will help speed up development. Using JavaScript allows us to use NodeJS and npm, so we can use packages to easily set up the server, connect to a database and other convenient utilities. We also considered Python for our server. It is also very simple to create a server in Python, especially using flask. However, the extra familiarity with the JavaScript language and the ease of using packages were enough for us to pick JavaScript as our language of choice.

As a startup, we need the maximum flexibility and the ability to reach our customers in a more suitable way. So a hybrid application approach is the best because it allows you to develop a cross-platform application in a unique codebase. The choice behind Ionic is Angular, I think that angular is the best framework to develop a complex application that needs a lot of service interaction, its modularity forces you (the developer) to write the code in the correct way, so it can be maintainable and reusable.

I had a goal to create the simplest accounting software for Mac and Windows to help small businesses in Canada.

This led me to a long 2 years of exploration of the best language that could provide these features:

  • Great overall productivity
  • International wide-spread usage for long-term sustainability and easy to find documentation
  • Versatility for creating websites and desktop softwares
  • Enjoyable developper experience
  • Ability to create good looking modern UIs
  • Job openings with this language

I tried Python, Java, C# and C++ without finding what I was looking for.

When I discovered Javascript, I really knew it was the right language to use. Thinking of this today makes me realize even more how great a decision this has been to learn, use and master Javascript. It has been a fun, challenging and productive road on which I am still satisfied.

Obviously, when I refer to Javascript, it is not without implying the vast ecosystem around it. For me, JS is a whole universe in which almost every imaginable tools exist. It's awesome - for real. Thanks to all the contributors which have made it possible.

To be even clearer about how intense I am with Javascript, let's just say that my first passion was music. Until, I find coding with Javascript! Yep, I know!

So in conclusion, I chose Javascript because it is versatile, enjoyable, widely used, productive for both desktop softwares and websites with ability to create modern great looking user interfaces (assuming HTML and CSS are involved) and finally there are job openings.

  • Client-Side: \ The form of our product is a web app because we would also provide a dashboard for displaying data and for some further purpose including data filtering and comparison. Hence, we would definitely use HTML5 for structuring the web, CSS3 for styling the web, and JavaScript for building the front-end logic. As for frameworks, we would use React because it is component-based that can keep our front-end code clean and organized. The virtual DOM of React also provides better efficiency in time when rendering the page. Furthermore, React has a greater number of users than Vue and Angular, thus have active communities for problem-spotting and problem-solving. We would also incorporate Bootstrap into our web app to provide an aesthetic user interface and thus to improve the user experience. The fact that Boostrap supports responsive site would also ease our workload if future adaptation for mobiles is needed.

What is Groovy?

It is a powerful multi-faceted programming language for the JVM platform. It supports a spectrum of programming styles incorporating features from dynamic languages such as optional and duck typing, but also static compilation and static type checking at levels similar to or greater than Java through its extensible static type checker. It aims to greatly increase developer productivity with many powerful features but also a concise, familiar and easy to learn syntax.

What is JavaScript?

JavaScript is most known as the scripting language for Web pages, but used in many non-browser environments as well such as node.js or Apache CouchDB. It is a prototype-based, multi-paradigm scripting language that is dynamic,and supports object-oriented, imperative, and functional programming styles.

What are some alternatives to Groovy and JavaScript?
Java
Java is a programming language and computing platform first released by Sun Microsystems in 1995. There are lots of applications and websites that will not work unless you have Java installed, and more are created every day. Java is fast, secure, and reliable. From laptops to datacenters, game consoles to scientific supercomputers, cell phones to the Internet, Java is everywhere!
Scala
Scala is an acronym for “Scalable Language”. This means that Scala grows with you. You can play with it by typing one-line expressions and observing the results. But you can also rely on it for large mission critical systems, as many companies, including Twitter, LinkedIn, or Intel do. To some, Scala feels like a scripting language. Its syntax is concise and low ceremony; its types get out of the way because the compiler can infer them.
Kotlin
Kotlin is a statically typed programming language for the JVM, Android and the browser, 100% interoperable with Java
Python
Python is a general purpose programming language created by Guido Van Rossum. Python is most praised for its elegant syntax and readable code, if you are just beginning your programming career python suits you best.
Gradle
Gradle is a build tool with a focus on build automation and support for multi-language development. If you are building, testing, publishing, and deploying software on any platform, Gradle offers a flexible model that can support the entire development lifecycle from compiling and packaging code to publishing web sites.
