It's probably a good time to start looking at using the Fetch API [1] for making AJAX requests instead of using jQuery or Backbone (or even XMLHttpRequest). Support seems to be growing quickly and Github's polyfill [2] can help cover the gaps.

Agreed... I really have come to like fetch, though I usually wrap it in a couple functions for my most common use cases... since some of the options are a little tedious to specify over and over again... such as `postJson(url, data)` which will post the data as json, and resolve the json response with some extra error handling.

It works well, and combined with babel for async/await, the workflow is pretty smooth as well.

Yes, EXCEPT, As of now fetch has no abort() support.

Having 50 in flight autocomplete requests going in parallel is not cool.
