Counting Button Clicks With JavaScript

Sometimes you need to know how many times the user clicks on an element. The most common solution is to create a counter as a global variable but with jQuery, you can prevent polluting the global scope by using data()to store the counter.

<!DOCTYPE html>
    <script src="
    <meta charset=utf-8/>
    <title>JS Bin</title>

<button>Click me</button>

        .data('counter', 0)
        .click(function () {
            var counter = $(this).data('counter');
            $(this).data('counter', counter + 1);
