Separation of Concerns in React: A New Paradigm

💡 Separation of Concerns in React: A New Paradigm 💡

In traditional web development, we’ve always separated HTML, CSS, and JavaScript into distinct files—each technology in its own place. This is how most of us learned web development, right?

But with the rise of interactive single-page applications (SPAs), this separation no longer made sense. Why? Because JavaScript became responsible for determining both the UI and the content. HTML, CSS, and JS became tightly coupled.

That’s where React stepped in, completely changing the game.

⚛️ React Components & JSX: Redefining Separation of Concerns React introduced the idea of co-locating data, logic, and appearance into one place—the component. Instead of separating technologies into different files, we now separate concerns based on components.

Each component in React represents one piece of the UI, and it contains everything related to that part—JavaScript, JSX (HTML-like syntax), and even some inline styles.

✨ A New Way of Thinking At first, many people were hesitant about mixing these technologies, believing we were throwing traditional separation of concerns out the window. But that’s not the case. React offers a different kind of separation—one concern per component rather than one concern per file.

Having all the relevant information about a specific part of the UI in one place has proven to be an incredibly efficient way of building modern web applications.

🚀 Co-location = Simplicity The concept of co-location—where things that change together are located together—works brilliantly in React. It makes our code easier to maintain, understand, and scale.

This new paradigm has become the foundation for not just React but many other modern frameworks as well.

So, what do you think? Have you embraced this new way of handling the separation of concerns? 🔥
