How do I promisify native XHR?

Answer 1

For anyone who searches for this now, you can use the fetch function. It has some pretty good support.

fetch('http://example.com/movies.json')
  .then(response => response.json())
  .then(data => console.log(data));

I've firstly used @SomeKittens's answer, but then discovered fetch that does it for me out of the box :)
