Events—How to Pull the Trigger
Getting bigger, pull the trigger
—Devo,
"Puppet Boy"
JavaScript has several built-in ways of reacting to user interaction and other events. To make a page dynamic and responsive, we need to harness this capability so that we can, at the appropriate times, use the jQuery techniques we have learned so far. While we could do this with vanilla JavaScript, jQuery enhances and extends the basic event handling mechanisms to give them a more elegant syntax while at the same time making them more powerful.
