If you still need to support old IE you can use a library like https://github.com/github/fetch
https://github.com/github/fetch or https://www.npmjs.com/package/fetch-ie8
https://github.com/github/fetch
Among countless others. Please don't bring in all of jQuery if you're just going to use one function from it.

To use Fetch in Firefox (38), you'll currently need to enable it — go to about:config, set dom.fetch.enabled to true, and restart the browser. To use Fetch in Chrome 41/Opera 28, you need to enable the "Experimental Web Platform Features" pref in chrome://flags.
