Kool-aid in the sense that JS is extremely attractive to MBA types that don't have to write anything with it. There is a huge pool of JS developers (quality is questionable but price range is mostly low), browsers run everywhere, Node.js made it possible to run the whole stack on it, so that's a win for MBA types and a great value proposition. The fact that it's a historically atrocious language doesn't matter as they have peasants (i.e. us) to deal with it (to be honest, it got much better since async/await was introduced, but hacks/warts are still there to be abused in horrible ways).

I wrote bleeding-edge games and other crazy stuff in JS you might be using right now in your business, so my opinion is not unfounded.
