Triggers a specific event on a given element, optionally passing custom data.

• Use the CustomEvent constructor to create an event from the specified eventType and details.
• Use EventTarget.dispatchEvent() to trigger the newly created event on the given element.
• Omit the third argument, detail, if you do not want to pass custom data to the triggered event.

const triggerEvent = (el, eventType, detail) =>
  el.dispatchEvent(new CustomEvent(eventType, { detail }));

triggerEvent(document.getElementById('myId'), 'click');
triggerEvent(document.getElementById('myId'), 'click', { username: 'bob' });
