Yeah, it's explicitly distinct from const a: String which says it won't change, and var a: String, which means this is legacy code that needs fixing.

If there's only two options you only need one keyword

[–] Lemminary@lemmy.world 1 points 2 days ago

Ah, but this is JS, so there are three options! And they all function entirely differently. And your assumptions don't apply, either. :D

True, but var and let are not same in js, so there is three.

if(true) {

var a = "dumdum"

}

console.log(a)

Is valid and functioning javascript. With let it is not.
