Unescape apostrophe (') in JavaScript?

Question

I\'m trying to unescape a HTML-escaped apostrophe (\"'\") in JavaScript, but the following doesn\'t seem to work on a devtools console line:

By using createElement like in T.J.'s answer, you open yourself up to XSS attacks.

DOMParser is a much safer way to correctly unescape HTML entities (including ')

function unescape(string) {
  return new DOMParser().parseFromString(string,'text/html').querySelector('html').textContent;
}

console.log(unescape('''));

You can use the function above with a string from any source, and the string won't be able to modify your page or steal data by including JavaScript.
