Trigger an event IMMEDIATELY on mouse click, not after I let go of the mouse - JavaScript?

Javascript Web Development Front End Technology Object Oriented Programming

For this, use the addEventListener() with mousedown event.

Example

Following is the code −

<!DOCTYPE html>
<html lang="en">
<head>
   <meta charset="UTF-8">
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <title>Document</title>
</head>
<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 href="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/css/bootstrap.min.css" rel="stylesheet" />
<body>
</body>
<script>
   document.addEventListener("mousedown", function () {
      console.log("Mouse down event is happening");
   });
</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.
