	* node makes use of synthetic events		* node makes use of synthetic events
	** generated by other code		** generated by other code

			==multitasking==
			* node is "cooperatively multitasked"
			* multithreaded code is preemptively multitasked
			* sane multithreading involves locking
			** temporary exclusive ownership
			** mistakes lead to race conditions
			* node avoids race conditions while being highly concurrent
			** node is fast

Created page with " ==Reactor pattern== * direct contrast to a procedural pattern * procedural: everything is synchronous ** each line completes before the next executes * reactor pattern: mostl..."

New page

==Reactor pattern==
* direct contrast to a procedural pattern
* procedural: everything is synchronous
** each line completes before the next executes
* reactor pattern: mostly synchronous
** exception: event handlers
** dispatcher calls event handlers
