Hemanth HM very succinctly shows off ES2021 features. Gosh it doesn’t feel like that long ago that all we could talk about is ES2015, and now that’s over a half-decade behind us.

There are new things like “arbitrarily chuck underscores in numbers.” I kinda dig that. Like 1_000_000_000 is the same as 1000000000 but more readable. To be honest, I barely even understand the other features.

It’s interesting to observe the JavaScript truck moving forward with new features, while also being around people that write Go a lot and how starkly different, philosophically, it seems to me. Like there is only one kind of loop in Go, a for loop, and that’s it, while JavaScript has a bunch of them—four just for Arrays! Go doesn’t add syntactic sugar on purpose, while JavaScript feels addicted to it. Sugar is a helluva drug.
