I'm diving into React and it's a whole new world compared to Object-Oriented Programming (OOP). I'm struggling to get my head around concepts like Dependency Injection (DI). Since functional programming doesn't typically use classes or interfaces (except in TypeScript), what are the alternatives to DI in this context? Also, I'm searching for a solid online guide that covers JavaScript from an OOP standpoint and includes best practices. I'm trying to build an app and things feel like they're getting chaotic fast!

You really don’t need to force an OOP mindset onto React. Think of a React component as just a function that takes props and returns HTML. One common approach in React is using reducers, which update a data structure through pure functions. It’s all about keeping state immutable—"useState” is pretty much just a basic form of a reducer that holds your state. For learning resources, I recommend checking out the React documentation; it's super comprehensive!
Oh, I almost forgot to touch on DI! In React, you can utilize the Context API for DI. Just set up your context at the root and you can access it throughout your component tree. It's like a singleton that provides whatever functionality you need. Make sure to keep it efficient since re-rendering everything can get unwieldy!
