Simple dialog boxes

Three methods allow you to display simple dialog boxes to the user. alert( ) lets you display a message to the user, confirm( ) lets you ask the user a yes-or-no question, and prompt( ) lets you ask the user to enter a single line of text. For example:

alert("Welcome to my home page!"); 



if (confirm("Do you want to play?")) {



 var n = prompt("Enter your name");



}
