MouseEvent not working in Internet Explorer

Question

Is it me? Is it my IE? or why is this code not working on IE 11:

var clicker = new MouseEvent(\"click\", {
  \'bubbles\': true,
  \'cancelable\': true,
  \'v         


        

Answer 1

There is a polyfill to make it work in IE.

Except that the try catch block in that code needs to look like this:

try {
  new CustomEvent('test');
  return false; // No need to polyfill
} catch (e) {
  // Need to polyfill - fall through
}
