[[pushBack]] does not support [[nil]] while [[set]] and [[a plus b]] do. For example:
<code>_array = [];
[[for]] "_i" [[from]] 0 [[to]] 3 [[do]]
{
_array [[pushBack]] [[nil]];
};
[[hint]] [[str]] _array; //[[hint]] is []</code>
<code>_array = [];
[[for]] "_i" [[from]] 0 [[to]] 3 [[do]]
{
_array [[set]] [_i, [[nil]]];
};
[[hint]] [[str]] _array; //[[hint]] is [any,any,any,any]</code>
<code>_array = [];
[[for]] "_i" [[from]] 0 [[to]] 3 [[do]]
{
_array = _array + [ [[nil]] ];
};
[[hint]] [[str]] _array; //[[hint]] is [any,any,any,any]</code>
That could be a problem if you're trying to standardize array length by filling empty elements with nil values. Use [[set]] for it's speed over [[a plus b]].

(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 = []; for "_i" from 0 to 3 do { _array set [_i, nil]; }; hint str _array; //hint is [any,any,any,any] _array = []; for "_i" from 0 to 3 do { _array = _array + [ nil ]; }; hint str _array; //hint is [any,any,any,any] That could be a problem if you're trying to standardize array length by filling empty elements with nil values. Use set for it's speed over a plus b.
