JavaScript Popup Boxes

JavaScript popup boxes are simple dialog boxes that appear on a web page. There are three main types of popup boxes in JavaScript: alert, confirm, and prompt.

1. Alert Box

• An alert box is used to display a message to the user.
• It only has one button, usually labeled "OK."

alert("this is an alert message!");

2. Confirm Box

• A confirm box is used to ask the user for confirmation (yes or no).
• It has two buttons, typically labeled "OK" and "Cancel" like yes or no

let result = confirm("u sure u wanna delete this");
if (result === true) {
  //user clicked OK
  // perform the delete operation
} else {
  // user clicked Cancel
  // do nothing or leave it
}

3. Prompt Box

• A prompt box is used to get input from the user.
• It has an input field for the user to enter data.

let age = prompt ('enter your age ')
