We'll assume some familiarity with HTML and JavaScript, but you should be able to follow along even if you haven't used them before.
If you need a refresher on JavaScript, we recommend reading [this guide](https://developer.mozilla.org/en-US/docs/Web/JavaScript/A_re-introduction_to_JavaScript). Note that we're also using some features from ES6, a recent version of JavaScript. In this tutorial, we're using [arrow functions](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Functions/Arrow_functions), [classes](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Classes), [`let`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/let), and [`const`](https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/const) statements.
