C vs C# vs JavaScript: What are the differences?

# Differences between C, C#, and JavaScript

C, C#, and JavaScript are three different programming languages that are used for various purposes. In order to understand their distinctions, let's delve into the key differences between them.

1. **Syntax**: C uses a procedural programming paradigm with a simple syntax, C# is an object-oriented language with a syntax similar to Java, and JavaScript is a scripting language with a syntax influenced by C.
   
2. **Memory Management**: In C, memory management is done manually by the programmer using functions like malloc() and free(), while in C#, memory management is handled automatically by the garbage collector, and in JavaScript, memory management is also automatic through garbage collection.
   
3. **Platform Dependency**: C is platform-dependent, meaning that the same code may not work on different platforms without modification, whereas C# is mostly platform-independent due to the .NET framework, and JavaScript is predominantly platform-independent as it runs in a web browser.
   
4. **Type System**: C is a statically typed language where data types are checked at compile time, C# is also statically typed but has support for dynamic types through the dynamic keyword, and JavaScript is dynamically typed where data types are determined during execution.
   
5. **Usage**: C is used for system programming and low-level operations, C# is commonly used for developing Windows applications and web services, and JavaScript is primarily used for client-side web development and server-side development with Node.js.
   
6. **Ecosystem**: C has a vast ecosystem with a lot of libraries and tools for system-level programming, C# has a strong support system from Microsoft with libraries like .NET framework, and JavaScript has a huge ecosystem with popular libraries like React, Angular, and Vue.js for web development.

In Summary, C, C#, and JavaScript differ in syntax, memory management, platform dependency, type system, usage, and ecosystem. Each language has its strengths and weaknesses based on the context in which it is used.

Advice on C#, C lang, JavaScript

Decided

C# and .Net were obvious choices for us at LiveTiles given our investment in the Microsoft ecosystem. It enabled us to harness of the .Net framework to build ASP.Net MVC, WebAPI, and Serverless applications very easily. Coupled with the high productivity of Visual Studio, it's the native tongue of Microsoft technology.

Needs adviceonPythonPythonJavaScriptJavaScriptDjangoDjango

I am currently learning web development with Python and JavaScript course by CS50 Harvard university. It covers python, Flask, Django, SQL, Travis CI, javascript,HTML ,CSS and more. I am very interested in Flutter app development. Can I know what is the difference between learning these above-mentioned frameworks vs learning flutter directly? I am planning to learn flutter so that I can do both web development and app development. Are there any perks of learning these frameworks before flutter?

Telegram Messenger has frameworks for most known languages, which makes easier for anyone to integrate with them. I started with Golang and soon found that those frameworks are not up to date, not to mention my experience testing on Golang is also mixed due to how their testing tool works. The natural runner-up was JS, which I'm ditching in favor of TS to make a strongly typed code, proper tests and documentation for broader usage. TypeScript allows fast prototyping and can prevent problems during code phase, given that your IDE of choice has support for a language server, and build phase. Pairing it with lint tools also allows honing code before it even hits the repositories.

JavaScript

C# (pronounced "See Sharp") is a simple, modern, object-oriented, and type-safe programming language. C# has its roots in the C family of languages and will be immediately familiar to C, C++, Java, and JavaScript programmers.

No description available.

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 C#, C lang, JavaScript?

Python

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.

PHP

PHP

Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world.

Ruby

Ruby

Ruby is a language of careful balance. Its creator, Yukihiro “Matz” Matsumoto, blended parts of his favorite languages (Perl, Smalltalk, Eiffel, Ada, and Lisp) to form a new language that balanced functional programming with imperative programming.

Java

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!

Golang

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.

HTML5

HTML5

HTML5 is a core technology markup language of the Internet used for structuring and presenting content for the World Wide Web. As of October 2014 this is the final and complete fifth revision of the HTML standard of the World Wide Web Consortium (W3C). The previous version, HTML 4, was standardised in 1997.

Scala

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.

Elixir

Elixir

Elixir leverages the Erlang VM, known for running low-latency, distributed and fault-tolerant systems, while also being successfully used in web development and the embedded software domain.

Swift

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.

Rust

Rust

Rust is a systems programming language that combines strong compile-time correctness guarantees with fast performance. It improves upon the ideas of other systems languages like C++ by providing guaranteed memory safety (no crashes, no data races) and complete control over the lifecycle of memory.
