One common and basic use of JavaScript is to create a pop-up window. Pop-up windows are a quick and simple way to add interactivity and capture your user's attention. To add a pop-up window to an HTML page, use the
script
tags and place your JavaScript code within the
script
element.
You can incorporate three types of pop-up windows in a webpage: an alert box, a confirmation box, and a prompt box. Use an alert box to display a message. This can be useful if you want to grab the user's attention with information about a special promotion. To create an alert box, use the alert( method. Following is an example of an alert box code:

   alert("Receive a 20% discount today!";

Use a confirmation box to confirm the user's action, such as to accept changes or to proceed to another page. To create a confirmation box, use the confirm( method. Following is an example of a confirmation box code:

if (confirm("Do you wish to proceed?" {
    alert("You selected OK";
}
else {
    alert("You chose to Cancel";
}

Use a prompt box to capture information from a user, such as a name, and then perform an action with the information. To create a prompt box, use the prompt( method. Following is an example of a prompt box code:

 var name = prompt("What is your name?";
if (name != null {
alert("Hello " + name;
}
else {
alert("You did not tell me your name. ";
}
