			Key difference between client-side and server-side JS: THE DOM
			* DOM = document object model
			* tree representation of an HTML document
			* with lots of access methods
			* purpose: read and change HTML page under control of JS

			jQuery
			* standardized methods for accessing DOM (and other stuff)
			* pattern: specify nodes => change nodes
			* specify nodes via tag, id, & class (same identifiers used by CSS)
