I have an async function declaration that works on Chrome and Firefox, but gives the following error in internet explorer.

SCRIPT1004: Expected ';'

File: javascriptFile.js, Line: 5, Column 7

This is the simplified version with these two function at the top of the file, and it still fails on internet explorer.

function sleep (ms) {
  return new Promise(function (resolve) { setTimeout(resolve, ms) })
}

async function begging (help) {
  await sleep(1000)
  console.log('please')
}

I can not seem to find anything about not being able to declare async functions in internet explorer. I would really appreciate any help at all, I'm not sure where to look next in order to figure this out.

Internet Explorer does not support async functions, and never natively will. The main drawback of using new JavaScript features is lack of support.
