jquery each() toggle class explanation?

[shortysbest]

Could somebody explain how part of this code works. Thanks.

 

$('.profile-show-posts li').each(function(){$(this)[$(this).attr('title') === ucwords(page) ? 'addClass' : 'removeClass' ]( 'current-page' ); });	

 

i know how most of this works, just I am not sure as to how the addClass : removeClass works. Like, what does the ? mark do for this function? What does the : mark do for this? What are the purpose of the [] brackets?

 

thanks.

The questions mark and the colon is the syntax for the ternary operator.

It's another way of writing an if else statement.

All objects in javascripts are associative array. myObject.property can also be referenced with myObject['property']

This is what the square brackets are doing.
