How to relate all Workspace Javascript as Java?

Question

I want to turn on all the javascript files in my IDE, like we do with Java in Eclipse. I’m trying to do this in Atom or Vscode. Some things I need:

• I want to link my variables and global functions, sometimes I use require.js but sometimes I add all the files .js in the index.html;
• With Ctrl + clique (or similar) I want to go to the implementation of the variable/method (regardless of whether it is in the same file or not);
• When using Ctrl + Space (or similar) after some object for example, I want to see all the attributes within it.

Is this possible? Especially using Atom or Vscode?
