JavaScript Generators Delegating to other Generator
Example
From within a generator function, the control can be delegated to another generator function using yield*.
function* g1() {
yield 2;
yield 3;
yield 4;
}
function* g2() {
yield 1;
yield* g1();
yield 5;
}
var it = g2();
console.log(it.next()); // 1
console.log(it.next()); // 2
console.log(it.next()); // 3
console.log(it.next()); // 4
console.log(it.next()); // 5
console.log(it.next()); // undefined
