Answer / Aman Kumar Chaudhary
In JavaScript, event handlers are used to execute code in response to user interactions or system events. Here's an example using a click event handler:
```javascript
// Get the button element
var myButton = document.getElementById('myButton');
// Define the function to be called when the button is clicked
function handleClick() {
alert('Button clicked!');
}
// Attach the function to the click event of the button
myButton.onclick = handleClick;
```
In this example, we first get a reference to the button with ID 'myButton'. We then define a function called `handleClick`, which displays an alert message when called. Finally, we attach the `handleClick` function to the click event of the button.
