What is console.log?

It's not a jQuery feature but a feature for debugging purposes. You can for instance log something to the console when something happens. For instance:

$('#someButton').click(function() {

  console.log('#someButton was clicked');

  // do something

});

You'd then see #someButton was clicked in Firebug’s “Console” tab (or another tool’s console — e.g. Chrome’s Web Inspector) when you would click the button.

For some reasons, the console object could be unavailable. Then you could check if it is - this is useful as you don't have to remove your debugging code when you deploy to production:

if (window.console && window.console.log) {

  // console is available

}
