Description
- Description:
- Applies given code to each element of the array and returns resulting array. The value of the current array element, to which the code will be applied, is stored in variable _x.
- Groups:
- Uncategorised
Syntax
- Syntax:
- array apply code
- 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:
- Array - resulting array
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]

- 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).
