Using the example of two of the most popular text editors, Visual Studio Code and Pycharm, we will talk about one important feature – commenting code in Java, Python, PHP, JavaScript, HTML, CSS.

A little bit about Visual Studio Code and Pycharm
Visual Studio Code (VS Code) is a powerful source code editor developed by Microsoft that runs on all popular operating systems: Windows, Linux, and macOS.

PyCharm is another Python development environment with support for the following languages: Rust, HTML, XML, JSON, YAML, SQL, JavaScript, TypeScript, CSS, Sass, SCSS, Less. It is important to note that PyCharm has two versions: free and paid. The range and availability of languages ​​depends on the version. The environment is available for Windows, macOS, Linux.

Why do we need comments in code?
Comments make code clearer, more accessible for you and others. You can and should comment code for several reasons:

Better understanding of code :
Comments are guides for other developers and you in the future. They help you understand what a particular piece of code does. This is especially useful in large projects or after a break.

Help with creating API documentation :
When creating libraries or APIs, comments become user instructions. They help other developers get a clear idea of ​​what the library or API can do.

Debugging and troubleshooting :
Comments are useful when debugging code and finding el salvador telegram data errors. Comments with explanations will speed up the process of eliminating errors.

Compliance with standards :
Comments can indicate adherence to coding standards, which in turn simplifies the process of agreeing on style and maintains consistency in the code.


Clear comments make the code less dependent on a specific developer. That is, it allows other developers to quickly continue development if the original author is unavailable.

By the way, you can not only comment on the code, but also uncomment it. Uncomment means transforming a comment into a part of the program, making it a "working" part.
