WHAT ARE PROPS IN REACT INTRODUCTION: React.js has revolutionized the way developers build user interfaces, offering a component-based architecture that promotes reusability and maintainability. Central to this architecture is the concept of "props" or "properties," which allow components to communicate with each other by passing data from parent to child. In this comprehensive guide, we will delve deep into the world of props in React, exploring their purpose, usage, best practices, and advanced techniques.
1.The Fundamentals of Props What are Props? Props are a fundamental concept in React that allow us to pass data from a parent component to its child components. They are immutable and provide a way to customize and configure child components dynamically.
How Props Work When a parent component renders a child component and passes props to it, the child component can access these props as properties of its "props" object. This mechanism enables the child component to render dynamically based on the data received from its parent.
Props in Action: Basic Example Let's explore a simple example to understand how props work in practice. We'll create a parent component and pass props to a child component to display dynamic content.
