What a Tool!

Issue #255  (Array.from(), Uncats, Git/CLI, Media)

One of the most welcome additions to JavaScript in recent years is a feature that allows you to convert an array-like object to an array. This is now possible using the Array.from() method, added in ES6.

Array-like objects are quite common in front-end applications. Here's a common example to demonstrate how this feature works:

function doSomething (a, b, c) {
  console.log(Array.isArray(arguments)); // false
  let args = Array.from(arguments);
  console.log(Array.isArray(args)); // true
}

doSomething(1, 2, 3);

View on JS Bin

The above code uses one of the most common array-like objects – the arguments object contained in all functions. You can see that the object is initially not an array, but after using Array.from(), it becomes a valid array. From there, I then have the option to use any array method to manipulate the collection.

Array.from() can convert any array-like object or any iterable object and convert it to an array. As of this writing, Array.from() doesn't seem to work on DOM collections, even though it seems like it should. But if you want to convert a DOM collection to an array, you can use the spread operator, another ES6 feature:
‚Äč
let myLinks = document.querySelectorAll('li a');

console.log(Array.isArray(myLinks)); // false

myLinks = [... myLinks];
console.log(Array.isArray(myLinks)); // true

Try on JS Bin

I'm not entirely sure why Array.from() doesn't work on DOM collections. Maybe it's not supposed to, or else browsers haven't implemented that yet. If you have any info on that, feel free to reply to this email. Nonetheless, the spread operator technique is simple enough and technically uses less code.
