16,976 PointsButton removal
The final function towards the end of the video has me somewhat confused: btn.addEventListener('click', (event) => { getJSON(astrosUrl, (json) => { json.people.map(person =>{ getJSON(wikiUrl + person.name, generateHTML); }); }); event.target.remove(); });
How is event.target.remove() removing the button?

4,379 PointsHi James, You set a listener on the btn. You told the listener to react when the btn is clicked.
btn.addEventListener('click');The 'event' is an object created when the listener detects the click.
(event)=>The 'event' object contains a property called 'target', which is a reference to the btn (The object which caused the event).
event.targetThe .remove() method is called on the 'event.target' - effectively removing the btn which caused the event.
