Warning about BIS event handlers:
+

BIS's event handlers (`addEventHandler`, `addMissionEventHandler`) are slow when passing a large code variable. Use a short code block that calls the function you want.

+ ```js + player addEventHandler ["Fired", FUNC(handleFired)]; // bad + player addEventHandler ["Fired", {call FUNC(handleFired)}]; // good + ``` +
+ ### 7.4 Hashes When a key value pair is required, make use of the hash implementation from ACE3.
