The CustomEvent() constructor creates a new CustomEvent.
- Based on MDN Docs
npm install --save-dev jspolyfill-custom-event
require( 'jspolyfill-custom-event' )();
Note: Make sure to add the extra set of parenthesis at the end to fire the function
that
registers the creation of the polyfill.
var event = new CustomEvent(typeArg, customEventInit);
