A very brief look into the Visual Studio Code editor:

It is made up of three main parts:

UI Framework
Editor
Engines 

The UI Framework is Electron, which is the same one that powers the Atom editor.
Electron is built on Chromium and Node.js

The editor is Monaco, which is the same one that powers Visual Studio Online

The engines are TypeScript Server and OmniSharp Roslyn

Open Source
Visual Studio is open source and available on Github

Insiders Builds
There used to be an Insiders program where you could sign up to gain access to the latest version a few days before anyone else. This is the same sort of idea as Chrome Canary or Firefox Nightly. Getting access to these latest builds is now even easier: just download the Insiders build.

Learning the keyboard shortcuts
Becoming productive in any editor involves learning at least the most commonly used keyboard shortcuts.

To view the full list of shortcuts in the operating system that you are currently using, see keybindings

Code also has built in support for Emmet (formerly known as Zen coding), which dramatically speeds up your HTML and CSS coding. The quickest way to learn these shortcuts is by reading the Emmet syntax guide.
