<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>");
   else
      document.write("<h1>Result is not correct</h1>");
</script> 
</html>

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.
