This is probably one of the most widespread code editors nowadays, although it has lost some momentum lately with users favoring other rising competitors such as GitHub's very own Atom. If this is your editor of choice, we will assume that it's already installed on your system and you also have Node (which is obvious, otherwise, you could have not installed TypeScript in the first place through NPM). In order to provide support for TypeScript code editing, you need to install Microsoft's TypeScript plugin, available at https://github.com/Microsoft/TypeScript-Sublime-Plugin. Please refer to this page to learn how to install the plugin and all the shortcuts and key mappings.

Once successfully installed, it only takes Ctrl + Space Bar to display code hints based on type introspection. On top of that, we can trigger the build process and compile the file to the JavaScript we are working on by hitting the F7 function key. Real-time code error reporting is another fancy functionality you can enable from the command menu.
