Explore React props in detail. Learn basics, examples, types, syntax, and how to use props in React components effectively with this guide.
Introduction
If you are learning React, one of the first and most important concepts you'll encounter is props. Short for "properties," props in React allow developers to pass data from one component to another, making components reusable, dynamic, and flexible.
In this blog, we'll dive deep into props in React, covering everything from the basics of React props to advanced use cases such as React props children, React default props, and the difference between React props vs state. We'll also provide multiple React props examples and explain the best practices for using them in both functional and class components.
What are React Props?
Props in React are arguments passed into components. They act like function parameters, allowing data to be passed from a parent component to a child component.
Example:
function Greeting(props) {
return Hello, {props.name}!;
}

Here, name is a React prop. The Greeting component receives it as input ...
... and displays the value.
React Component Props
React component props make components customizable. Instead of writing multiple similar components, you can create one flexible component and pass different props.
Example:
function Button(props) {
return {props.label};
}

Both buttons reuse the same component but display different labels thanks to props.
