addEventListener() and removeEventListener(); 

These methods exist on all DOM nodes and accept three arguments: the event name to handle, the event handler function, and a Boolean value indicating whether to call the event handler during the capture phase (true) or during the bubble phase (false);

to add an event handler for the click event on a button, you can use the following code:

1 var btn = document.getElementById("myBtn");
2 btn.addEventListener("click", function() {
3     alert(this.id);
4 }, false)
