As applications scale, it is inevitable to introduce statefulness into your applications to make sure data is passed around correctly between the different components to ensure they interact in the intended way. Incorrect handling can lead to bugs, app crashes which could be glitchy at best, but can take down entire services and cause revenue loss at worst.
In this talk, we’ll go over state management in ReactJS in depth and understand how it works under the hood. We will start off by familiarizing ourselves with simple API like the useState hook, and then go on to examine complex examples like setting up contexts and reducers. We’ll walk through an open source ReactJS project Builder Book and look at how states are used in it.
