In the ever-evolving landscape of web development, certain technologies rise to the top, capturing the hearts and minds of developers worldwide. One such technology is React.js, often referred to simply as “React.” Created by a Facebook software engineer named Jordan Walke in 2011, React has grown into the most commonly used web framework, surpassing even jQuery, according to Stack Overflow’s latest annual Developer Survey. In this blog post, we’ll explore why developers are enamored with React and why learning it is a smart move in today’s tech ecosystem.
React.js revolves around components, which are like Lego bricks for web development. Developers create small, reusable, and independent components, each with its own properties and functions. These components can be combined to form larger UI elements, making the code modular and easier to maintain.
const element = <h1>Hello World!</h1>;
React.js introduces the concept of a Virtual DOM, a lightweight version of the actual DOM. It compares the current Virtual DOM tree to the new one and updates only what has changed. This process, known as reconciliation, enhances performance and responsiveness.
React.js applications are Single Page Applications (SPAs), where all front-end code is downloaded locally when a user accesses the website. This approach minimizes server requests, resulting in faster loading times. SPAs handle front-end rendering intelligently, re-rendering only what has changed when users switch views. React-Router, a popular library, manages navigation in React.js SPAs.
Before creating custom components, developers can explore a vast library of existing React.js resources. Here are seven examples:
