//In JavaScript, an iterable is an object that can be used in a for-of loop. It has a method called Symbol.iterator that returns an iterator, which is an object with a next method that returns the next value in the sequence.

​

// Here is an example of how to create an iterable:

​

const iterable = {

  [Symbol.iterator]: function() {

    let i = 0;

    return {

      next: function() {

        return {

          value: i++,

          done: i > 3

        };

      }

    };

  }

};

​

for (const value of iterable) {

  console.log(value);

} // Output: 0, 1, 2

​

​

// Arrays, strings, and maps are all iterable in JavaScript. You can use the for-of loop or the forEach method to loop over the elements of these objects.

//Iterable objects are objects that can be iterated over with for loops

​

//Technically, iterables must implement the Symbol.iterator method.
