What are props in React?

Comment

Props are inputs to components. They are single values or objects containing a set of values that are passed to components on creation using a naming convention similar to HTML-tag attributes. They are data passed down from a parent component to a child component.

The primary purpose of props in React is to provide following component functionality:

Pass custom data to your component.

Trigger state changes.

Use via this.props.reactProp inside component's render() method.

For example, let us create an element with reactProp property:

This reactProp (or whatever you came up with) name then becomes a property attached to React's native props object which originally already exists on all components created using React library.

props.reactProp

import React from "react";
import ReactDOM from "react-dom";

class ChildComponent extends React.Component {
  render() {
    return (
      <div>
        <p>{this.props.name}</p>
        <p>{this.props.age}</p>
      </div>
    );
  }
}

class ParentComponent extends React.Component {
  render() {
    return (
      <div>
        <ChildComponent name="John" age="30" />
        <ChildComponent name="Mary" age="25" />
      </div>
    );
  }
}
