Text editors

Regarding text editors, you can use any editor to work with Angular as well as Ionic. You can also try Sublime text (http://www.sublimetext.com/3) or Atom editor (https://atom.io/) or Visual Studio Code (https://code.visualstudio.com/) for working with the code.

If you are using Sublime text, you can take a look at: https://github.com/Microsoft/TypeScript-Sublime-Plugin to add TypeScript intelligence to your editor. And for Atom, refer to the following link: https://atom.io/packages/atom-TypeScript.
