What are the differences between normal and slim package of jquery?

Looking at the code I found the following differences between jquery.js and jquery.slim.js: In the jquery.slim.js, the following features are removed: jQuery.fn.extend jquery.fn.load jquery.each (attach a bunch of functions for handling common AJAX events) jQuery.expr.filters.animated AJAX settings (jQuery.ajaxSettings.xhr, jQuery.ajaxPrefilter, jQuery.ajaxSetup, jQuery.ajaxPrefilter, jQuery.ajaxTransport) XML parsing (jQuery.parseXML), Animation effects (jQuery.easing, jQuery.Animation, jQuery.speed)
