To start your journey with React, please go through the React Quick Start Tutorial, including all of its sections:
At various points, the tutorial provides links to CodePen snippets showing how the code executes. When you don’t feel comfortable just reading the code, be sure to try to the CodePen to see if that helps you better understand things.
If you still don’t understand things, then post your questions to the class Slack workspace in the #react channel.
By the time and date indicated on the Schedule page, be sure to have completed this assignment. You do not have to turn anything in to Laulima, but the information presented in this Quick Start is crucial to further progress in React.
