There are two things. One is IDE (Integrated Development Environment) and another is Editor. The example of IDE is Visual Studio, Eclipse etc. The example of editor is Notepad, Notepad++ etc.
Code editing redefined and optimized for building and debugging modern web and cloud applications.— Visual Studio Code
In Microsoft developer community ‘Visual Studio’ is very popular (if you are a developer who is not working with Microsoft technology, you can still use Visual Studio for Android, iOS development). Now Microsoft is providing a new editor to the developers. The name is ‘Visual Studio Code’. It is not powerful like ‘Visual Studio’. It is light weight. It is only an editor. One thing to be noted is that it can be installed in Mac, Linux as well.
Visual Studio Code is free and available on your favorite platform — Linux, OS X, and Windows— Visual Studio Code
It supports major programming languages. You can get IntelliSense support while you are typing your code in ‘Visual Studio code’. Some language also support some advance features like ‘Refactoring’ and ‘find all references’.
The installation is very fast and it updates automatically itself (only Mac and Windows). If you have ‘Git’ installed on your computer ‘Visual Studio Code’ will work best with it. For any kind of light code writing or editing ‘Visual Studio code’ is a welcome addition in Microsoft tools stack. We need to wait and see the future of this editor.
