What are the best JavaScript IDEs and editors?

I'm currently developing a JavaScript editor in JavaScript (chromium) for JavaScript programmers. My goal is to make a editor that does deep static code analysis to generate function list, function argument helper, find misspelled properties and smart code completion.

When I started I looked at like hundred editors and the best one that had was I was looking for was Visual Studio, and currently visual studio Code, witch has actually improved since I started working on my editor. And it's also open source. But it's written in type-script while my editor is in vanilla JS.

I'd like to add a "pro" for Codelite: the person who maintains it is very responsive when it comes to bug reports. Until a few months ago, the nodejs debugger had some fairly serious issues. Each of the problems I reported was addressed and resolved within days.

It installs sublime and preloads it with a stack of useful extensions for web development.
