A Guided Walk Through React
This is a short group of demos using React to create a site to store information about computer science legends. The first playback shows how to create a component with props. The second playback adds state to the CS legends site. The third playback integrates the site in an express app.
The last playback is an exercise. It shows how to create a countdown timer component that can be started and stopped. The exercise asks you to extend the app to make a sport's team scoreboard.
