Visual Studio Code, also known as VS Code, is a free open source source code editor from Microsoft, which is offered under the MIT licence. It supports almost all common programming languages with syntax highlighting, auto-completion and functions specific to the respective programming, scripting or markup languages. Visual Studio Code has become a popular editor for programmers and is available for Linux, Windows and Mac.
VS Code is not a development environment (like the Visual Studio software of almost the same name), but it offers IDE-like functions by means of plugins.
"Apart from the name and some functions like IntelliSense, VS Code has nothing in common with Visual Studio. Unlike Visual Studio, VS Code does not work with project files, but on the basis of code files and folders." (Source)
VS Code cannot be installed directly from the official package sources. However, there is either a DEB package directly from Microsoft or alternatively an external package source, which is not provided by Microsoft.
DEB package from Microsoft VS Code can be downloaded and installed from the project page as a .deb package.
