Answer 1

There's a FormData polyfill that works. For details, read their docs.

IE 10, IE 11 and Edge

To make it work with IE 10 and above, you'll just have to add a WeakMap polyfill as well.

JSBin demo for IE10 and above.

_{Code above picks up the latest versions. Versions tested: https://unpkg.com/weakmap-polyfill@2.0.0/weakmap-polyfill.min.js and https://unpkg.com/formdata-polyfill@3.0.9/formdata.min.js}

IE11 and Edge, only (if you don't have to support IE10):

If you only need IE 11 and above, you can remove the WeakMap's polyfill and just keep FormData's.
