// In the HTML there are several elements containing the
// text "Click Me". Those elements are followed by another element
// containing the number zero, which we'll call the "counter".
var counter=0;
//
// Inside the anonymous function below, write the necessary code so
// that clicking any "Click Me" element will increment its paired
// counter.
//
// BONUS 1: Create a new element on the page that displays the sum of
// all other counters.
//
// BONUS 2: When the global counter goes above 10 add the "goal" class
// to it. Doing so should make it turn red.
(function() {
console.log("Welcome to the Exercise");
var el = document.querySelector(" p button");
// Your code here.
el.addEventListener("click", function(event)
{
console.log( "event triggered on:", event.target );
}, false);
