Limit number of checkable boxes

Here is a simple JavaScript code snippet that limits the number of checkboxes that can be checked at any one time. In this example, the limit is set to 3 checkboxes.

This code creates a simple HTML page with 5 checkboxes. When a user tries to select more than the allowed number of checkboxes (in this case, 3), an alert will be displayed, and the latest checkbox selection will be undone.
