How to relate the entire Javascript workspace to Java?

I want to link all javascript files in my IDE, as we do with Java in Eclipse. I'm trying to do this on Atom or VSCode. Some things I need:

• I want to bind my variables and global functions, sometimes I use require.js but sometimes I add all files .js to 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 attributes within it.

Is this possible? Especially using Atom or VSCode?
