Hello, I am still a student and would like to ask a question. Currently, I am developing in mobile development with Flutter in the frontend and Python in the backend part. Right now I have to make a choice about developing a mobile app or developing a backend to progress more professionally. My questions are as follows:

1) If I prefer the mobile application area, will I only work with the Ui/Ux developer with the front-end and code the designs in Swift Kotlin languages, am I responsible for the back-end software?

2) I have a product that generates new ideas so I like to control the development and work there because the backend is the brain, but are they independent from each other in the backend mobile application? Is the mobile app developer responsible for the backend software?

3) I don't like graphic design because I don't like it if it's not perfect and I get stressed. Am I responsible for the graphic design in the mobile app?

4) Is a mobile app developer also a backend developer?

I know these are very simple questions, but they are very important to me. Thanks for your answers.

Hi Hüseyin! 1-2) In my experience If you are a Mobile Applications Developer you will have the following responsabilities: - Develop (not designing) both functionality and screens of the app you are working - Consume (not develop) third party or self company owned APIs or Backend services - Distribution tasks. - Mantainance tasks. Now, there will always be companies wishing you know the whole thing (ui/ux, backend, frontend, mobile, cd/ci, data science, etc.). And of course it will be helpful for you to know a little bit of the stuff around mobile development, but it's not very common since it's not part of the responsabilities of a mobile app dev.

3) No, you are not responsable for the designs of your application, that's why companies have Product designers, ux designers, ui designers for preparing the screens, logos, color palettes, etc for products. As a developer your job is to see and examine the designs and take them from Figma, InVision, Zeplin, etc to the Code editor.

4) This is the thing, if you are working as a Mobile Developer you might know about Mobile development, not backend, not frontend, not ui ux. BUT if you know a little about backend that might be helpful although backend should not be your responsability.

I hope this makes sense to you. Cheers!

As a mobile developer, I'm usually a member of a larger team and it's usually another person's responsibility to develop the backend/API, and another person's to do the UX/design. Very very few teams use cross-platform tools like Flutter or React Native, because tools like those tend to make mediocre apps that scale poorly and are impossible to debug, so make sure to get familiar with Swift/iOS or Kotlin/Android (or both).

Hi! I think most of your questions led to these answers:

  • Mobile software developers don't responsible for the back-end part, or even graphic design. Of course, the back-end part should be done by a back-end developer. The graphic design, I'd say that if you work on a start-up, you might be the one who does since there isn't much manpower there, but in the larger company, they would have a designer especially in UI/UX. You'll have a mockup for the application that you need to follow. As a developer, you're expected to code, not design.

  • I've said that the responsibility isn't yours, but of course, you'll have an advantage over others if you know UI/UX, or back-end as well. That would help you a lot to be a good mobile developer.

Good luck!

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.

Hope it helps!

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.

Hey there, we are looking to develop our own layer 1 blockchain. We're splitting the responsibilities for origination, clearing, and settlement across three independent but cooperating node networks. We've gotten our Proof of Concept up using Ruby on Rails for the nodes, you can see it as the attached link. So far, so good. Now we are looking to convert it into a distributable and are trying to figure out which language is the best for this.

Essentially our needs from the language are: solid networking tools and speed, very fast execution of basic actions, some parallel execution, and able to compile the end product into an easy to distribute and use package for end users.

I was learning Rust, but I have a healthy amount of experience with Swift and right now, it's only me coding. I've only done iOS coding, but have built a fintech app from scratch that's now in the app store so I'm pretty familiar with the language and its benefits. Haven't experimented with Vapor or any of the application development tools, and I wanted to know if it is a crazy idea to develop a blockchain node in Swift instead.

Pick Rust. Rust can provide all what you need and has been a major language in blockchain/cryptocurrency industry. Swift is slower than Rust and does not have such support in the networking and domain field. Swift tooling is great only on macOS, therefore you are likely to have troubles on other platforms.

You can use swift of course. It’s more of a question of being performant.

You really want to try some basic operations and find what’s most performant for you.

Rust is wonderful for cloud applications requiring heavy concurrency, it has compile time checking for such things.

Go and C++ could be more performant in your case. Swift is really quite an obtuse language, with a lot of features, some which may complicate your implementation.

Also, you want to consider the market of developers who could help build it. If you use Go or C++ there is a larger collection of people who know the languages than there is with swift.

Since you're following Python, I would recomend using Django as your main back-end language. If you know Python it would be a great experience. Django is well documented on their official website: https://www.djangoproject.com/ I would also use React for front-end as well.

Since your team is already using JavaScript, there's a great number of examples for backend services written with NodeJS. I'd recommend using Firebase, or any backend as a service (you can use that term to find alternatives), for setting up your backend as it is much easier for newer people to understand and lets you focus on your core application logic, and not provisioning servers, databases, etc.

I am new to programming and am a university student. While Computer Science is not my area of study, I am majoring in a subject that branches off computer science and health informatics, which deals with databases. I am currently in a programming fundamentals course at my university. My instructor mentioned that he develops in Java, but I have heard many good things about Python and JavaScript before taking his course; while we are only doing the fundamentals, I believe he is teaching us some in Java.

Since I am new to this, I'm not sure what I like more. I have also been self-teaching before this course but have not gotten deep into a particular language's fundamentals. I want to decide on a language and stick to it before I move to a new one after the first language is learned, but it is difficult deciding which language to start with. I want to develop medical software and medical mobile apps.

There's a reason many universities start with Java- it has strict rules and lays out code in a straightforward (if excessively-boiler-plate-heavy) way. For a beginner, Java is an excellent way to learn the fundamentals of programming before taking off the training wheels and continuing in more flexible, less-syntactically-rigorous direction like Python or JavaScript.

Sticking to a language before moving on is a common goal. However, in reality you are going to transition as you find languages that better suit you or your organization's requirements. Start with Java, not because it is optimal for your end goals, but because it will teach you what you like and dislike about programming and because your instructor is more familiar with it. That will give you a valuable perspective and allow you to make a more informed decision later.

There are many ways to solve problems in different languages, but the "best" language pragmatically is the one that you feel most comfortable using. In that respect, programming is like woodworking- you want to let the tool do the work. If there is another language that is "better" objectively but more difficult or confusing to you, you will counteract the anticipated benefits by having to struggle to write code.

The only way to solve this problem while avoiding opinions and tastes is to objectively look at what you are trying to build.

Thus the most efficient part of your question is your last sentence: you want to build medical software and medical mobile apps.

In that case, the answer is definitely Java, as is for all "real" software projects.

Python is good for data science, in other words for statistics. Its other competitive advantage is that it is easy to learn for beginners, but that would be a bad reason to use it for a "real" software project.

JavaScript is a mess you don't want to get into. The major reason why it's popular is that many people learn it first, because its very basic features are easy to learn, although they don't get you far, and because it used to have exclusivity on the web. But in reality it will make your life a lot harder after a few weeks, without any benefit. I know I'll get criticisms for that, but I stand fully by this position.

Since you're already taking a CS course which involves Java, I would recommend you to keep learning it. Java's statically typed & OO nature forces you to learn a lot of important yet common programming fundamentles. C++, C# and Java type languages also force you write code more carefully (you have to think about the data types on your own and even allocate/de-allocate memories [C++ pointers]). That's why colleges prefer it as go to language for teaching CS concepts.

On the other hand, JS, Python and other such languages are dynamic in nature and hence, easy to learn. But you can't learn certain concepts (polymorphism, abstract classes, diamond problem etc) using these languages. So it makes sense to stick with Java in your case.

While I've seen many people recommend Java (and I agree with them), I think you can learn both. But it depends on how much time you got. I recommend you first learn Java. Then python will be easy to learn, and focus mainly on modules for graphs. The reason why I recommend to learn both is because python is much better and easier to code about statistical analysis. But again do this only if you have time to just learn them.

If your project doesn't have anything to do with statistics and data analysis (I'm pretty sure you do though), learn only java. Also if you are wondering why I never mentioned JavaScript (JS), it's because i really don't recommend it. JS is much harder to learn and requires a lot of lines of code to do simple things.

My advice to anyone learning to program is to not obsess on the language.. You SHOULD learn all languages.. Same as learning human spoken languages - the more you learn, the more ways your mind can interpret a new problem set. Learning them at the same time isn't a big deal (just like growing up in a bilingual home). Your language and your software stack are guaranteed to change 3 times in your career. Don't assume you're going to choose the "right one". And you wont waste any time learning one you never wind up using.

As a person who works on linux and OSX desktops, I have a personal bias against working for companies and software stacks that require C# or Visual Studio. But this is not due to their technical merits, but instead the OS as a platform condusive to efficient CLI toolchains and container management. But aside from that, I can use vi/IntelliJ-suite to write most languages, so language isn't a real concern. If you're windows bound, pretty much everything is available to you (through VMs and docker).

Ideally you do at least SOME full stack development learning. This means you'll need javascript, and thus nodejs would be a good stack to learn. If you ultimately like gaming or 3D, you might need C# and certainly python.

Any AI (which is a hot employment topic for the forseeable future) would like python skillz.

I personally love Java (and Android's Kotlin varient) for it's very very well designed multi-threaded libraries. go and rust are newer and thus do a slightly better job at this, but due to the open-source nature of java and editors that auto-reveal function call source code, it's very easy to learn how vendors implemented MT code and various other algorithms. Python should be equally "open" to 3rd party library review (and thus again how they solve complex problems), though a lot of times, I see python resorting to compiled C-libraries (and thus the cost to crack open the code and or trace through the code becomes too burdensome to bother).

Although java seems to be a good fit for you. It is a cumbersome language to get started out. It will be far easier for you to learn Python and stick with it long term. This is due to the fact you will be easily able to google things for python and you will spend less time learning the language, and more time using it to do what you want.

Making mobile apps is easier with Java due to the fact that google does not directly support app building with python. If this is your biggest priority stick with Java.

Javascript: This language is the best language to learn if you are making a website. However, for easy of use you can do all the database access stuff with python. And send back the data to your website. Javascript is also another cumbersome language in my opinion.

Each language has its use. If I were In your situation, I would choose the language that's easy to start with.

Decisions about Java, Python, and Swift

I wanted to develop a student app that possibly could be used by many teams (students from other schools)

I chose Ionic, because:

  • single codebase: previously, we used React Native for Android and Angular for web/PWA, which was troublesome

  • portability: runs on PWA (which is important, because iOS license is too expensive for school app), web, Android iOS (+ others, if needed)

  • full use of web technologies: Next.js, Tailwind, React in this example (in oppose to Flutter/Java/Kotlin)

  • stability and maintainability: low-entry level due to basic web technologies without new syntax (in oppose to React Native and Flutter), web is really stable and won't lose support (which doesn't have to be true with Flutter/Dart)

I've yet to see a non-native application that I felt performed as well and/or provided the same user experience with Cordova/PhoneGap/Xamarin. Frankly, at best they all seemed like underpowered web applications deployed to a sandbox that ran on a phone. They didn't feel "slick" or "mobile-first" and in some cases the performance was unacceptable. At previous companies, we built a few of these apps at the client's insistence, and in every case, they re-engaged us about 18 months later to re-write the app(s) natively.

We are doing some research on React Native and Flutter, but I am not yet convinced that they can provide the same level of experience and performance as native, though I am trying to keep an open mind.

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.

I have been working with React Native since 2016 and originally I had to use simulators in Xcode, install pods on top of node packages, configure certificates, and more abundant objectives that take time away from actual development. As a development studio, we have to move quick and get projects to our clients and partners in a matter of months.

Expo made this easy for us. We now have a mobile app for clients to download and test their project on, there is no need to install pods or configure Xcode, and development is super fast and reliable now.

Founder & Developper at Finance D · | 71 upvotes · 216.9K views

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.

What is 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!

What is 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.

What is Swift?

Writing code is interactive and fun, the syntax is concise yet expressive, and apps run lightning-fast. Swift is ready for your next iOS and OS X project — or for addition into your current app — because Swift code works side-by-side with Objective-C.

What are some alternatives to Java, Python, and Swift?
C lang
Abstract
Abstract builds upon and extends the stable technology of Git to host and manage your work.
Golang
Go is expressive, concise, clean, and efficient. Its concurrency mechanisms make it easy to write programs that get the most out of multicore and networked machines, while its novel type system enables flexible and modular program construction. Go compiles quickly to machine code yet has the convenience of garbage collection and the power of run-time reflection. It's a fast, statically typed, compiled language that feels like a dynamically typed, interpreted language.
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
