I agree, and this is something also I have witnessed in my own Electron project, where careful care was taken to write fast and memory efficient code. It doesn't really use that much memory compared to native applications when running, I've done comparisons.

I feel also that the problem is more with the style of javascript development rampant these days, where not a lot of care is taken into making memory efficient or even efficient code.

This has to do a lot of course with the high rise in people studying to become (mostly) web-developers, without any deeper degree in CS or understanding of how computers really work.
