Hi Bessie Wong 👋

OK 👍

However, I‘m not sure if that was necessary. You can see the vanilla JS and CSS in the demo pen by using the View compiled JS/CSS option.

As for the JavaScript syntax. Those are actually features of JavaScript.

const for defining read-only variables. And then the second part of that snippet is using Object destructuring.

Destructuring assignment

const

As for the CSS, stylus has been used to reduce the amount of code that was written 👍

Hope that helps! 😃
