ES6 class methods not returning anything inside forEach loop

Question

For some reason the method getTwo() inside the PollClass won\'t return 2 but undefined. If I put the return

Answer 1

An arrow function is still a function, and you're only returning from the forEach callback function, not from getTwo, you have to return from the getTwo function as well.

It's not quite clear why you would use a loop to check for something in that way, but the concept would be something like

getTwo() {
    var n = 0;
    this.nums.forEach(num => {
      if (num === 2) n = num;
    })
    return n; // returns something from getTwo()
  }
