If you will start a project from scratch I recommend to use TypeScript. But, If you work with legacy projects written in JavaScript I recommend Flow (JS). Both tools have the same objective: reduce the bad code (which create illegible code, generate bugs e problems to maintenance). Flex helps you to avoid fall in bad codes, but TypeScript prevent you to c you to create bad codes. I believe cause this some JavaScript fans don't like TS, because TS block you to write some types o code. This is the fundamental difference between TS and Flow: Flow avoid problems, but no force. TS force you to prevent problems.

Visual Studio Code , beyond to be one of the major, complete and best IDEs to code frontend, VSCode has awesome plugins to work with Angular 2 . I tried to use Atom too, but Atom to works Angular 2 is still growing yet. So far, the best is VSCode :)

Both are very good! But I started with Visual Studio Code when I started to work with AngularJS 4. I tried to use Atom too, but at that time Atom did not have good Angular plugins, in the other side VS Code has nice plugins for Angular. I do not know how is Atom now a days about this, but I think that it must have evolved.
