C++ vs JavaScript vs Python: What are the differences?

  1. Syntax and Structure: In C++, the syntax is strict and requires the use of semicolons at the end of each statement, whereas JavaScript and Python use indentation to define blocks of code and do not require semicolons.

  2. Type System: C++ is a statically-typed language, meaning data types need to be explicitly declared, while JavaScript and Python are dynamically-typed, allowing variables to change types during execution.

  3. Memory Management: C++ requires manual memory allocation and deallocation using new and delete keywords, whereas JavaScript and Python have automatic memory management through garbage collection.

  4. Concurrency: C++ supports multithreading and multiprocessing with libraries like pthreads, while JavaScript is single-threaded but can achieve concurrency through asynchronous programming with callbacks and promises, and Python has a Global Interpreter Lock (GIL) that limits multithreading.

  5. Performance: C++ is generally faster and more efficient due to its compiled nature, direct memory manipulation, and closer hardware interaction, while JavaScript and Python are interpreted languages, resulting in slower performance.

  6. Usage: C++ is typically used for system programming, game development, and performance-critical applications, while JavaScript is mainly used for web development and browser-based applications, and Python is favored for data analysis, machine learning, and scripting tasks.

In Summary, C++ is a statically-typed language with manual memory management and strict syntax, while JavaScript and Python are dynamically-typed languages with automatic memory management and more flexibility in syntax and structure.

What is C++?

C++ compiles directly to a machine's native code, allowing it to be one of the fastest languages in the world, if optimized.

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 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 are some alternatives to C++, JavaScript, and Python?
C lang
C#
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.
Node.js
Node.js uses an event-driven, non-blocking I/O model that makes it lightweight and efficient, perfect for data-intensive real-time applications that run across distributed devices.
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.
PHP
Fast, flexible and pragmatic, PHP powers everything from your blog to the most popular websites in the world.
