You can joke about it, but there is absolutely a lot of value in the fact that you can just fire up a debugger against Electron or React or your devtools or Node itself. The "just" is doing a lot of heavy lifting here of course, but I've done all of the aforementioned at different points of my career, to reasonably good success. I don't think everything should be written in Javascript, but at times it's been very convenient that that's what's under the hood.
