The form is one of the most-used HTML elements in web development.
Since the introduction of React, the way forms have been handled has changed in many ways.
In React, there are two ways to handle form data in our components:
The first way is the Controlled Component:
We handle form data by using the state within the component to handle the form data.
The Second way is Uncontrolled Component:
We let the DOM handle the form data by itself in the component.

Uncontrolled Component

Code Snippet

Controlled Component

import React, { Component } from 'react';

class App extends Component {
    state = {
        message: ''
    }
    updateMessage = (newText) => {
        console.log(newText);
        this.setState(() => ({
            message: newText
        }));
    }
    render() {
        return (
            <div className="App">
                <div className="container">
                    <input type="text"
                        placeholder="Your message here.."
                        value={this.state.message}
                        onChange={(event) => this.updateMessage(event.target.value)}
                    />
                    <p>the message is: {this.state.message}</p>
                </div>
            </div>
        );
    }
}

Props or properties in react are a functional argument by which different components communicate with each other.
Props is just a data/information that allows us to pass in JSX tags.
With the help of props, we can pass values like JavaScript objects, arrays or functions, etc.
