How do I trigger a function when the time reaches a specific time in JavaScript?

Javascript Web Development Object Oriented Programming

For this, extract the time of specific date time and call the function using setTimeout(). The code is as follows −

Example

<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta name="viewport" content="width=device-width, initialscale=1.0">
<title>Document</title>
<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>
<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/fontawesome/4.7.0/css/font-awesome.min.css">
<style>
</style>
</head>
<body>
<script>
   function timeToAlert() {
      alert("The time is 9:36 AM");
   }
   var timeIsBeing936 = new Date("08/09/2020 09:36:00 AM").getTime()
   , currentTime = new Date().getTime()
   , subtractMilliSecondsValue = timeIsBeing936 - currentTime;
   setTimeout(timeToAlert, subtractMilliSecondsValue);
</script>
</body>
</html>

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