Props

Props (short for properties) are a fundamental concept in React and similar component-based frameworks, used to pass data from a parent component to a child component. They are read-only and immutable within the child, enabling a unidirectional data flow that helps manage state and UI updates predictably. Props allow components to be reusable and configurable by accepting different inputs to render dynamic content.

Also known as: Properties, Component Props, React Props, Vue Props, Angular Inputs

Why learn Props?

Developers should learn and use props when building applications with React, Vue, Angular, or other component-based libraries to create modular, maintainable code. They are essential for passing data like user information, configuration settings, or event handlers between components, enabling dynamic rendering and interaction without tightly coupling components. For example, in a React app, props can pass a list of items to a child component for display, making the child reusable across different parts of the application.
