Here are few of the features that makes Visual Studio Code as a IDE of choice for me.
It runs on Windows, Linux and Mac. Personally I am an owner of Windows devices always and have used Windows as a development machine since ages. Though for mobile development I am thinking of a Mac purchase soon.
Support of GIT. I have a git repository at https://github.com/Hozefam and plan to upload most of my useful projects up there soon.
VS Code is based on the Electron Software framework which makes usage of Node.js a breeze!!!
More of a Command line interface which makes things a lot geekier.
Personally, I am a big fan of Visual Studio family of IDEs and have been using it since 12years now. Its more of a second nature that I cannot adjust to any other IDE.
