Is there something in ES6 to collect iterator including the final return value?

If I have a following generator:

function* generate() {
    yield 1;
    yield 2;
    return 3;
}

Is there something built in in ES6 to get [1, 2] and 3 out of it (without doing next manually)?
If I only needed 1 and 2 I could use for(of), but I want to get 3 as well.

Generators are not designed to work that way. If you want to get all the values at once, then I hardly see the point of using generators. If you must, you can do something like this -

function* generate() {
    yield 1;
    yield 2;
    return 3;
}

var arr = [], k, it = generate();
do {
   k = it.next();
   arr.push(k.value);
} while (!k.done);

console.log(arr);
