Here's another practical and relatively new array method that's now supported in all modern browsers: The Array.values() method. This method returns an array iterator object that iterates each value in the array.

Here's an example:

let fruits = ['apple', 'orange', 'kiwi', 'banana'];
let myIterator = fruits.values();

for (let value of myIterator) {

The above code uses a for...of loop to log each of the values of the array, one at a time. As you can see, this is a really easy way to iterate through all of an array's values.

As mentioned, the method returns an iterator object. This means instead of using a loop to automatically go through the values, you can use the iterator.next() method, which allows you to move to the next item in the array as needed.

Note the following code:

let vegs = ['celery', 'carrot', 'lettuce', 'radish'];
let myIterator2 = vegs.values();

/* output:
  "value": "celery",
  "done": false

You can try both of the above examples in this CodePen demo.

In the latter example, notice in the demo that I'm using the next() method five times. This takes the iterator through all the elements in the array. Each move through the array returns an object with two key/value pairs: The current item and a Boolean indicating whether the iteration is "done".

Once the iterator is done, it will no longer iterate the items and it won't return any values. This is the case whether you're using a loop or the next() method on the iterator object.

A couple of other things to note:

  • When iterating through sparse arrays (i.e. arrays with empty slots), the empty slots are treated the same as undefined (that is they are iterated to).
  • If you use a break statement to end iteration, you can continue iterating where you left off.

Overall this seems like a useful feature, particularly the ability to loop through all the items quickly and cleanly.

A Tweet for Thought

This is easily my favourite GitHub Copilot joke so far. Certainly some truth to it, though I would imagine some took exception to the implication.
