Enter values with prompt and evaluate on the basis of conditions in JavaScript?

Let’s say we are getting two values with prompt −

var firstvalue = parseInt(prompt("Enter the value1"));
var secondvalue = parseInt(prompt("Enter the value2"));

 Live Demo

<!DOCTYPE html>
<html lang="en">
   <meta charset="UTF-8">
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
   var firstvalue = parseInt(prompt("Enter the value1"));
   var secondvalue = parseInt(prompt("Enter the value2"));
   if (firstvalue * secondvalue > 50)
      document.write("<h1>Result is correct</h1>");
      document.write("<h1>Result is not correct</h1>");

To run the above program, save the file name anyName.html (index.html). Right click on the file and select the option “Open with Live Server” in VS Code editor.
