In React, components can receive information from a parent component by utilizing props (short for properties). A prop is an object accessible to all React components. It serves as a means to pass data from a parent component to a child component.

<Welcome fullName = "Ashish Bhardwaj" />

In the provided code, the prop `fullName` is passed with the value “Ashish Bhardwaj” to the `Welcome` component, and accessing this prop is demonstrated succinctly.

props = { fullName: "Ashish Bhardwaj" }

In case of functional components, we can access a prop value as shown below.


Example: Below is the basic implementation of the React Props.


import React from "react";
import ReactDOM from "react-dom";
import App from "./App";
        <App fullName={"Ashish Bhardwaj"} />



import React from "react";
function App(props) {
    return (
        <div style={{
            color: "green",
            textAlign: "center"
            <h1 style={{
                color: "red",
            }}>Hello {props.fullName}</h1>
            <h2>App to GeeksforGeeks</h2>
export default App;
