A while ago, I wrote an article about Using Context API in React. However, most of my examples on that page used Class components, static contextType, and Consumer, which is a legacy way of dealing with Context and in TYOOL 2021 we want nice, clean, functional components. I needed to...

Using React hooks like useState makes it easy to manage things like a shopping cart, but that state may only be available one instance at a time. What if we wanted that state to be available between multiple pages? We can take advantage of React's Context API which lets us extend our c...
