jQuery: What's the difference between after() and insertAfter()

Question

jQuery has an .after() method, and also an .insertAfter() method.

What\'s the difference between them? I think I can use .after()

Answer 1

( after & before ):

$('selector').after('new_content');
$('selector').before('new_content');

while ( insertAfter & insertBefore ):

$('new_content').insertAfter('selector');
$('new_content').insertBefore('selector');
