Jquery DOM Manipulation
The jQuery function (usually aliased as $) can be used both to select elements and to create new elements.
You can optionally pass a second argument with element attributes:
'< a >' --> The first argument specifies the type of DOM element you want to create. In this example it's an anchor but could be anything on this list. See the specification for a reference of the a element.
The 'name':'value' pairs will appear between the < > of the first argument, for example < a name:value > which for our example would be
