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.
In fact, Go uses
for
as syntax sugar for other loopsA true smattering of new features.
The “minor, but useful convenience”.
The “I didn’t know I needed this”.
The “finally addresses this pain point”.
The “why wasn’t this in before?”, alternatively “finally they put this in”.
The “so esoteric, neither you, nor anybody you know knows what it does”
