(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]

Note that pushBack does not create a new object.
Therefore, if you edit an object that was pushed back to an array, it also affects the object in the array. e.g.
_first_squence = [1,2,3]; _second_squence = [5,4]; _first_squence pushBack _second_squence; systemChat str _first_squence // prints [1,2,3,[5,4]]] reverse _second_squence; systemChat str _first_squence // prints [1,2,3,[4,5]]]
If you pushBack an array for instance, you can just copy it to generate a new object. e.g.
_first_squence pushBack +_second_squence;
