Excuse my naïvety, but I find Flutter/Dart documentation very intuitive and easy to use in VS Code. Same goes for Android Studio when I was using it. Now using VS Code for javascript and Parse Cloud code there is almost zero documentation. Am I doing something wrong or is there a plugin for javascript to get more data? Same goes for Atom which I was using initially and gave absolutely zero documentation for javascript even with some autocomplete plugins.

This makes it extremely difficult to learn the APIs. Is there a plugin for javascript that I'm unaware of?

Flutter package documentation on hover:

Flutter autocomplete (also shows more data about method if available):
