I would say VS Code is far more performant than the Jetbrains editors in my experience on a 2013 MBP. It may be that the Jetbrains editors are "doing more", but I always found them frustratingly sluggish - maybe a worthwhile trade off when using something like Scala but I personally couldn't deal with it for Javascript.
I'd really recommend trying it again. On a performant machine, VS Code feels like a native app to me aside from a slightly slower start up time, whereas Atom is noticeably slow. On my bottom spec 12" Macbook the difference is more noticeable, but everything feels slow on there.
