Disclaimer: this workshop is outdated and unmaintained. It hasn't changed since 2018, so I strongly recommend using my new Learn React workshop instead.
An introductory workshop for FAC students to learn about React.
We'll be writing our code in a single index.html file for now. There are three scripts included on the page: React, ReactDOM and Babel. The first two expose React and ReactDOM as globals. The Babel script allows us to use a special <script type="text/babel"> to have our JS 'transpiled' into standard ES5. This will let us write ES6 and other React specific syntax.
This set-up is simpler to jump into without having to learn about complex build-systems when you are really trying to learn React. It also demonstrates that React isn't something magical that requires modern JS and WebPack etc. It's just a JavaScript library that you can include in an HTML page.
This is in no way a best practice, so please don't build a real app this way :)
We'll look at Bundlers a bit later on, and will eventually modularise our code using Parcel.
If you're finished early check out these entries in the React Docs. They give a slightly higher-level look at how you should think about building React apps:
