You're encoding more information in the typescript one. You're saying it's a string that will get updated.

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

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.

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