First off, JS is a perfectly usable language. In some respects, it's even great: of the "big three" scripting languages (Python/Ruby/JS), it's the only one that got Lambdas right, and also got closures right (unlike, say, Python). It has sometimes-quirky syntax, and some odd semantics, but they don't bite as often as you'd think.
Second off, I would say that this article is right about the bulk of Electron: It's a pretty massive thing to lug around with your app, and not ideal in any sense. However, if you want to build a UI very fast, there is nothing better than HTML/CSS for it. Except maybe TK.
Speaking of TK, I would actually advocate TK over Electron: it's easy to use, has bindings to pretty much every language out there, and with TTK, it doesn't look like crap.
Finally, "considered harmful" essays rarely do any good, and frequently do harm.
So yes, while I usually like Drew's writing (at least a little: he's good, but far from the best), I wish he had spent the time he spent writing this doing more work on SCAS.
Seriously. If SCAS was actually done, and documented, and usable, that would be great. There is a freaking vacuum of good assemblers for the platform: another one would be nice.
