Other Methods to Iterate through Generator Objects

For...Of

Notice how the For...Of statement is used to iterate through a Generator Object:

function* genFunc(){
    yield 'a';
    yield;  
    yield* [1,2,3];
    yield 123;

    return "finished";

}

for (var x of genFunc()){ //for...of statement
    console.log(x); 
}
//Outputs:
//'a'
// undefined
// 1
// 2
// 3
// 123
// <-- return value is not outputted

Spread Operator (...)

Notice how the spread operator is used to iterate through a Generator object:

function* genFunc(){
    yield 'a';
    yield;  
    yield* [1,2,3];
    yield 123;

    return "finished";

}
var arr = [...genFunc()]; //...spread operator
// arr = ['a',undefined,1,2,3,123]

Destructuring

Notice how the destructuring assignment is used to iterate through a Generator object:

function* genFunc(){
    yield 'a';
    yield;  
    yield* [1,2,3];
    yield 123;

    return "finished";

}

var [a,b,c,d,e,f,g] = genFunc(); //destructuring assignment
// a = 'a'
// b = undefined
// c = 1
// d = 2
// e = 3
// f = 123
// g = undefined <-- g is undefined because there are no more yields
