In React, events are the triggers that cause a function to be called in response to a specific action. Examples of events include clicking a button, hovering over an element, or pressing a key.
To handle an event in a React component, you define a function that serves as the event handler and attaches it to the event using the on
prefix and the event name, such as onClick
or onChange
. When the event occurs, the event handler function is called with an event
object that contains information about the event, such as the event type and any data associated with the event.
Here is an example of a button element with an onClick
event handler in a React component:
import React from 'react';
function MyButton() {
function handleClick(event) {
console.log('Button was clicked');
}
return (
<button onClick={handleClick}>Click me</button>
);
}

When the button is clicked, the handleClick
the function will be called and the message "Button was clicked" will be logged to the console.
