because they're doing different things. Web page: Wait for data from server, update page to match, this usually happens at most every few seconds. (or if it's server based) Fetch data, format into html, set to browser Game: For 10s to 1000s of objects, run some code for each one at 60 frames a second. That code is usually one or more finite state machines and/or co-routines per object (or some hacked together code that effective does the same). This code updates a bunch of state for each object, and then other code displays the current state. They're doing different things so they take different approaches. PS: I get the above is over simplified.
