_array1 append _array2is 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. - Posted on May 21, 2015 - 10:27 (UTC)

Array "unshift" implementation using append, a faster 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 }; // Example arr = [1,2,3]; [arr, 0] call KK_fnc_unshift; //both arr and return of function are [0,1,2,3] - Posted on May 21, 2015 - 15:21 (UTC)

Array "insert" implementation using append, much faster alternative to BIS_fnc_arrayInsert:
KK_fnc_insert = { private ["_arr", "_i", "_res"]; _arr = _this select 0; _i = _this select 2; _res = []; _res append (_arr select [0, _i]); _res append (_this select 1); _res append (_arr select [_i, count _arr - _i]); _res }; // Example arr = [1,2,3,4]; [arr, ["a","b"], 2] call KK_fnc_insert; //[1,2,"a","b",3,4] - Posted on May 21, 2015 - 15:52 (UTC)

A faster alternative to BIS_fnc_arrayPushStack using append:
KK_fnc_pushStack = { _this select 0 append (_this select 1); _this select 0 }; // Example arr = [1,2,3]; [arr,[4,5,6]] call KK_fnc_pushStack; //both arr and function return are [1,2,3,4,5,6]
