Examples
function-star notation
function* generator() {
yield 1;
yield 2;
yield 3;
}Duck typing
function generator() {
var i = 0;
var content = [1, 2, 3];
return {
next : function () {
var res;
if (i < content.length) {
res = { done : false, value : content[i] };
} else {
res = { done : true };
}
i++;
return res;
}
};
}
