Symbol and for of overload in js?

Question

JavaScript

Hello.
Do I understand correctly that the following code:

let obj = {
  to: 10,
  [Symbol.iterator]: function () {
    let curr = 0;
    let stop = this.to;

    return {
      next() {
        if (curr <= stop)
          return {
            done: false,
            value: curr++
          }
        else
          return {
            done: true
          }
      }
    }
  }
}

for (let num of obj) {
  console.log(num);
}

is it actually an overload of the for of loop?

Answer 1

Well, you can call it that. In fact, this is the use of language tools to pass through the iterator. In JS, there is no formal concept of "overloading" but informally - call it whatever you like.
What exactly is the question?
