(A3 1.26) It is recommended to use pushBack instead of BIS_fnc_arrayPush.
_array = [1,2,3]; _array pushBack 4; //same as [_array, 4] call BIS_fnc_arrayPush;

- It's highly recommended to use the new pushBack command, up to 43% faster than set and up to 11843% faster a plus b!

pushBack does not support nil while set and a plus b do. For example:
_array = []; for "_i" from 0 to 3 do { _array pushBack nil; }; hint str _array; //hint is []

Array "push" implementation using pushBack, alternative to BIS_fnc_arrayPush
KK_fnc_push = { _this select 0 pushBack (_this select 1); _this select 0 }; // Example arr = [1,2,3]; [arr, 4] call KK_fnc_push; //both arr and return of function are now [1,2,3,4]

Array "shuffle" implementation using pushBack, much faster alternative to BIS_fnc_arrayShuffle:
KK_fnc_shuffle = { private "_cnt"; _this =+ _this; _cnt = count _this; for "_i" from 1 to _cnt do { _this pushBack (_this deleteAt floor random _cnt); }; _this }; // Example arr = [0,1,2,3,4]; arr call KK_fnc_shuffle; //[3,2,4,0,1]
