Javascript yield from the function nested inside generator

Question

This code generates an error:

function *giveNumbers() {
    [1, 2, 3].forEach(function(item) {
        yield item;
    })
}

This is probabl

Answer 1

You can also use while and pass arguments as such (Demo)

function *giveNumbers(array, start) {
    var index = start || 0;
    while(array.length > index + 1) {
        yield array[index++];
    }
    return array[index];
}


var g = giveNumbers([1,2,3], 0);

var finished = false;

while(!finished) {
    var next = g.next();
    console.log(next.value);
    if(next.done) {
        finished = true;
    }
}
