detailed description
Most jQuery traversal methods manipulate an instance of a jQuery object and generate a new object that matches a different set of DOM elements. When this happens, the new set of elements should be pushed into the stack held in the object. Each successful filter method call pushes the new element onto the stack. If we need the old set of elements, we can use end () to pop up the new collection from the stack.
Examples are as follows:
P {margin:10px; padding:10px;}
Hello, how are you?
$("p"). Find ("span"). End (). Css ("border", "2px red solid")
