Props in React JS stands for “properties”. They are read-only objects that are passed from a parent component to a child component. Props can be used to pass data, functions, or other objects to the child component.
Props are similar to function arguments in JavaScript. They are passed to the component as an object, and the component can access the props object using the this.props property.
Props are immutable, which means that they cannot be changed after they are passed to the component. This ensures that the child component cannot modify the data that it receives from the parent component.
Props are a powerful way to pass data between components in React JS. They allow you to decouple your components and make your code more reusable.
Here is an example of how to use props in React JS:
const ParentComponent = () => {
const name = "John Doe";
return (
<ChildComponent name={name} />
);
};
const ChildComponent = ({ name }) => {
return (
<div>
Hello, {name}!
</div>
);
};
In this example, the ParentComponent passes the name prop to the ChildComponent. The ChildComponent then uses the name prop to render the text “Hello, {name}!”.
Here are some of the benefits of using props in React JS:
They allow you to decouple your components.
They make your code more reusable.
They help you to keep your data consistent.
They make it easier to test your components.
If you are new to React JS, I recommend that you learn more about props. They are a powerful tool that can help you to build better React applications.
