The current way we handle the click event for our buttons is inefficient because for each customer on the page, we have a separate delete button with a separate event handler function in memory. This consumes more memory as the number of customers increases.
We can optimize this by changing the selector to the customers table and providing a filter as the second argument of the on method. With this implementation, no matter how many customers we have on the page, we will have only one click handler for all delete buttons.
In this example, our handler is hooked to the table with the ID 'customers'. We have a filter in this one handler, so the callback function will be called only if the click event is raised from an element matching the selector.
To further optimize our code, we can use a jQuery plugin called data tables, which provides pagination, sorting, and filtering functionalities right out of the box.
