For features such as expansion help (e.g. when you type a dot after a parameter name inside a function), you still need static analysis.

But your point stands: JS IDEs can and should go beyond “edit-compile-debug” (which has become so mainstream that many people forget about languages such as Common Lisp and Smalltalk).
