Doesn't work for any of my JS projects. However, Brackets and WebStorm work just fine. It does work for my TypeScript projects.

Edit: It does work on some symbols in JS projects. But it doesn't work on function calls. Example: 'object.methodName()' I can't click on methodName and have it find the source. Brackets and WebStorm find all possible definitions, if there is only 1, it will take you directly there, if there are multiple, then you get a list to choose from
