Nice :)
We can also replace chars that we don't know with either mapped char or with a ?
?
'Wół'.replace(/[^a-zA-Z]/g, c => mapping[c] ?? '?')
Hey Kostia,
currently trying to understand your code. Do you mean || instead of ??.
||
??
Hey, Michael!
Yeah, in this particular case || would work as well as ??. Nullish coalesce would be useful if you have a mapping that simply drops some char, e.g:
mapping
const mapping = { ą: "a", ć: "c", ę: "", // <-- drop ę ł: "l", // etc ... };
Here || wont work. But that's just a case I made up 🙂
Awesome, thanks for that!
I didn't know that JavaScript added a nullish coalescing operator in ES2020! Currently running Node 12, I should probably update it, too!
Yeah, JS is getting hard to track :)
Also note ?. conditional chaining — helps a lot!
?.
And they've added more operators just recently (@ stage 4):
||= &&= ??= for conditional assignment (dunno why...)
||=
&&=
??=

{| }
Thanks for the summary!
I already use the ?. in my TypeScript projects, will have a look at the other ones!
