React has always been great for reusing and composing components. That means you can write a piece of UI and simply reuse it later on. Moreover, your component can have some embedded logic that you can reuse too. Write once, and use everywhere. A big win! But what if you want to reuse the logic only? It means that you don’t care about the UI, but you care about the behavior of the component. Can you still write it once and use it everywhere?
One of the things I enjoy the most about coding is discovering patterns. Being aware and mindful of the patterns emerging in your codebase can make it easier to keep that codebase consistent, readable and easy to navigate. Most patterns will remain unspoken, and some, that prove notably elegant, are named and promoted as best practices. Others might even be candidates for a basis of a new abstraction, although I recommend restraint as it’s worth remembering that abstractions are expensive.
