Can there be generator getters in classes?

Question

I mean getters that are generators. All this is ES6+ I believe. Like this maybe.

class a {
    get *count() {
        let i = 10;
        while(--i) yield i;         


        

Answer 1

There is no shorthand notation for this. You can however return a generator from a getter property without any difference:

function* countdown(i) {
    while(--i) yield i;
}
class a {
    get count() {
        return countdown(10);
    }
}

I would recommend to avoid this though. Getters that return distinct stateful objects on consecutive calls can be quite confusing.
