Join Joe Chellman for an in-depth discussion in this video Implement states, part of React for Web Designers (2018).
- [Instructor] In this video we're going to implement state…for the first time in one of our components.…When your component needs to track state,…which React keeps track of and reacts to,…you need to use a class.…So, we'll be converting the product customizer…into a class, so it can track the data we need…to keep track of in this little, mini application as state.…So, once again, we know we need to keep track of…the current color, the available colors, the current size,…and the currently available sizes.…
Switching back to the code, we've previously decided…that we want that color and size information…to be stored at the product customizer level,…so it will be available to all these child components.…When you get to the point that you need…to implement this state, these functional components…are no longer sufficient.…So, we need to convert product customizer into a class.…If we were using ES6 directly, we'd be able…to create a class…called "ProductCustomizer,"…which extends the built-in "React.component" class.…
