This week we'll be going over how to pass information between components. We will learn how props work and introduce ourselves to our first React Hook, useState!
We will also cover some JSX knowledge left out of last week: event handling and how to use the JavaScript.map() array method with JSX. By learning these items now, we can apply our new knowledge immediately!
Through these new concepts a component will be able to update information within its parent. Specifically, it can update the parent's state. We'll also go over how a component can update its siblings' information through the siblings' props.
Objective:
- Introduce props and state
- Show how we can update a parent's state through its child
- Show how a child can update its siblings props
- Go over event handling and using `.map()'
Homework:
Create a video player to serve as practice for updating sibling props
