Heeeere's Johnny!

_array1 append _array2 is roughly 1.2x faster (depending on array size) than _array1 = _array1 + _array2(Averaged over 10.000 iterations with two identical arrays containing the numbers 0 through 9)
The larger the arrays to append, the faster append is as it does not create a new array, which happens with array addition.

Array "unshift" implementation using append, alternative to BIS_fnc_arrayUnShift KK_fnc_unshift = { private ["_arr", "_tmp"]; _arr = _this select 0; _tmp = [_this select 1]; _tmp append _arr; _arr resize 0; _arr append _tmp; _arr };
