Learn React Props in 5 Minutes

React is a popular JavaScript library for building user interfaces. One of the key concepts in React is the use of props, which are short for properties. Props are a way to pass data from parent components to child components in React.

What are Props?

Props are used to pass data from one component to another in React. They are similar to function arguments in JavaScript, and can be any type of data, such as strings, numbers, objects, or even functions.

Passing Props

To pass props from a parent component to a child component, you simply add the prop as an attribute to the child component. For example:


<ChildComponent propName="value" />


Then, in the child component, you can access the prop using the props object:


function ChildComponent(props) {
return <p>The value of propName is {props.propName}</p>;
}


Using Props

Once you have passed the props to the child component, you can use the data within the component to display information or perform other tasks.

Conclusion

Props are an essential part of building dynamic and reusable components in React. By understanding how to pass and use props, you can create more flexible and efficient React applications.
