Why Do We Need Front-End Frameworks Like React?

Ever wondered why we use frameworks like React instead of just sticking with Vanilla JavaScript? Let’s look at how front-end development has evolved to see why frameworks have become essential.

A Look Back: Before 2010, websites were mostly rendered on the server. The browser would receive static HTML, CSS, and JavaScript to display content. JavaScript’s role was minimal, limited to small dynamic effects, often using libraries like jQuery.

The Shift: As JavaScript usage grew, web applications started feeling more like native apps, which led to the rise of single-page applications (SPAs). With SPAs, the browser took over rendering, creating smoother, more responsive apps.

The Complexity of Vanilla JS: Managing a complex app’s UI using just Vanilla JavaScript? Not easy. As apps grew, keeping the UI in sync with ever-changing data without a framework quickly turned into a mess of tangled code.

Enter Frameworks Like React: React and similar frameworks tackle this challenge head-on by efficiently syncing the UI with data. They allow developers to focus on building great user experiences rather than wrestling with the underlying complexities.

Frameworks also help organize code and enforce best practices, resulting in cleaner, more maintainable code that’s easier for teams to work with.

👉 So, why React? Because it takes care of the hard parts—syncing UI with data—leaving us free to focus on what matters: creating amazing applications.
