Learn how React.js state works with examples. Explore state in ReactJS, component state, and practical tutorials for building interactive apps.
Introduction
In modern web development, ReactJS has become one of the most popular JavaScript libraries for creating dynamic and interactive user interfaces. One of its core concepts is ReactJS state, which plays a vital role in making components dynamic and responsive. Without state, a React application would simply render static content, offering no interactivity.
This guide provides a complete explanation of state in ReactJS, practical examples, and insights into its usage. Whether you’re learning through a React JS state tutorial or building your first React website, mastering state will give you the ability to control how your application behaves in real time.
What is State in ReactJS?
The state in ReactJS refers to an object that stores dynamic data for a component. Unlike props, which are immutable, the state can change during the lifecycle of a component. These changes trigger re-renders, allowing the user interface to update automatically.
For example, if you are building a React website with a button that tracks the number of times it has been clicked, that button would use state to store and update the count value.
