What is the JavaScript version of sleep()?

Javascript Web Development Front End Technology

The JavaScript version of sleep() is “await”. The await feature pauses the current aync function.

Example

You can try to run the following code to implement sleep in JavaScript

<!DOCTYPE html>
<html>
   <body>
      <script>
         function setSleep(ms) {
            return new Promise(resolve => setTimeout(resolve, ms));
         }
         async function Display() {
            document.write('Wait for 5 seconds!');
            await setSleep(5000);
            document.write('After 5 seconds!');
         }
         Display();
      </script>
   </body>
</html>
