Example usage

Consider the following example:

const fruits = ['apple', 'banana', 'cherry'];

const iterator = fruits[Symbol.iterator]();

console.log(iterator.next().value); // Output: 'apple'
console.log(iterator.next().value); // Output: 'banana'
console.log(iterator.next().value); // Output: 'cherry'
console.log(iterator.next().value); // Output: undefined

In the above code snippet, we create an array fruits containing three elements. We then call fruits[Symbol.iterator]() to get the iterator object. Finally, we use the next() method on the iterator object to move through the array and print the corresponding values.

Conclusion

The Array.prototype[@@iterator]() method is a powerful tool for iterating over the elements of an array. It provides a convenient way to loop through the array without having to rely on traditional for or while loops. By using this method, you can easily access and manipulate the values stored in an array, enhancing the functionality and versatility of your JavaScript code.
