Its quite embarrassing how badly Atom performs, how many subprocesses it opens and how much memory it will happily leak during the X hours its in use. I really wouldn't consider using anything NW/node-webkit or the like for all but the most trivial of applications.

There are definitely ways to incorporate Javascript into "native" programming. In Yosemite you can write Javascript that directly loads and calls native frameworks (like you can with Python/ Ruby). If you wanted you could write an entire application in Javascript, but taking shortcuts and trying to use HTML and the DOM for your interface only leads to these sorts of severe issues when doing anything nontrivial.
