Introduction to Reactjs
ReactJS is a JavaScript library designed for building user interfaces, emphasizing a component-based system and unidirectional data flow. It utilizes JSX to combine HTML with JavaScript, and its Virtual DOM provides a lightweight abstraction for efficient rendering. While React offers significant advantages such as simplicity and SEO benefits, it lacks a full application framework as it primarily serves as a view layer.
