Python absolutely has async/await/promises, and it's actually quite a lot worse than JavaScript in this regard because Python _also_ has synchronous APIs and _no_ tooling whatsoever to make sure you don't call a sync API in an async function thereby blocking your event loop (which, if your application is a networked service with any amount of traffic at all, will typically result in a cascading failure in production). I'm no great fan of JavaScript, and I've written _wayyyyy_ more Python than JS, but async/await/promises is exactly the wrong example to make the case that Python is better.

Structured concurrency with Exception groups make it untouchable for JS. If JS implements structure concurrency like Python, Java, Kotlin, then maybe it can be viable.
