- Syntax:
- Syntax needed
- Parameters:
- array: Array - array of Anything
- code: Code - code to be executed on each element of the array. Current element value is stored in variable _x

- Return value needed
Examples
- Example 1:
_arr = [1,2,3,4,5,6,7,8,9,0] apply {[1,0] select (_x % 2 == 0)}; //[1,0,1,0,1,0,1,0,1,0]- Example 2:
_arr = [1,2,3,4,5,6,7,8,9,0] apply {_x ^ _x}; //[1,4,27,256,3125,46656,823543,16777216,387420480,1]- Example 3:
_arr1 = []; _arr1 resize 20; _arr2 = _arr1 apply {0}; //[0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0]- Example 4:
[0,1,2,3,4] apply {str _x}; // Returns ["0","1","2","3","4"]

- if performance really is an issue, apply seems to be (very) slightly faster than forEach (by more or less one percent, 0.7-1.5% in my tests to be precise).
