New JavaScript syntax 

ES2021 was just approved and is finally, FINALLY shipping with String.prototype.replaceAll. So

'falafel'.replace(/l/g,'b')
'falafel'.replaceAll('l','b')

both give you `fabafeb`.

No more regex needed just to get the "greedy" flag in there!

New JavaScript syntax 

@darius how many years until the JavaScript standard library is usable enough to not require a million npm packages installed?

New JavaScript syntax 

@meena I think it's already there and we just have some very bad habits ingrained (and lots of very common dependencies don't use the new JS syntax themselves, so then THEY install those dependencies even if you don't)

New JavaScript syntax 

@darius i think I'm mostly thinking of mutable by default (array) functions
which seems like a bad thing in… most languages

New JavaScript syntax 

@meena @darius Yeah, lots of languages have mutable by default lists/arrays and JS isn’t alone in that.

One option is that the ES2015 “spread” operator makes it really easy to do a lot of common JS arrays things immutably-ish without using an outside library. const newList = […oldList, newItem] and things like that.

@darius 1. Nice! Shouldn't need a regex just for that.
2. I saw the URL and at first thought you hashtagged #stringprototypereplaceall (very niche of you)

New JavaScript syntax 

@darius wow, great achievement. Saved so many lives.
