Call the generator from the generator

Question

Call the generator from the generator

I would like to call a generator from another generator by getting its "steps". Although I can't seem to find a good syntax for this.

function* test1() {
    yield 2;
    yield 3;
}
function* test2() {
    yield 1;
    for (var i of test1()) yield i; // WTF
    yield 4;
}
var a = test2();
for (var b of a) {
    console.log(b);
}

Output: 1 2 3 4

How can I shorten this line?

You can use syntax yield*

with just yield* test1()
