i have heard best condense javascript 1 file reduce number of http requests application makes. however, hold true if make use of event listeners each specific 1 page of site? for example, have 3 different pages make ajax requests load random picture server. first page listens button click, second page listens mouseover, , third page listens change in value of select field. make sense have 1 giant js file contains dom-manipulation logic, event listeners? or better define necessary dom-manipulation logic in 1 file , have 1 small js file each page page-specific event listeners page. tl;dr: event listeners elements not exist on page cost more in performance http requests additional js file? reduction of number of requests 1 reason consolidating javascript files one. the other reason this: javascript file can, after browser has downloaded once, retrieved browser cache when subsequent pages use it. fewer files means more streamlined caching. the cost of little javascript...
