We saw how to react to DOM events.

I want to add a line about writing your own custom events.

You can use the Event object which is provided by the browser, to create a new event, in this case the event named “start”:

const anEvent = new Event('start');

Once you have the event, you can trigger the event using

document.dispatchEvent(anEvent)

and when this happens, any event listener listening on that event “name” is triggered:

document.addEventListener('start', (event) => {     
  console.log('started!')
})
