> So imagine you are using something like React/Angular or other templates you want your IDE to understand this templates and not highlight the syntax as errors, if you use a function/object defined in a js file in a template you want the IDE to make the connection. So when you want to see where a symbold defined in a .js file is sued you want to be found int the template file. You could have 2 different components that both have a thing called name - you want the IDE to not confuse this and consider this 2 different things as the same but be correct.

Why imagine? I have emacs open and it's doing this with React right now (tide mode).
