Description
- Description:
- Function to find item in nested arrays and return a path to the first match.
In some cases findIf might be the better way of finding a nested element. It is a lot faster! - Execution:
- call
- Groups:
- Arrays
Syntax
- Syntax:
- [array, query] call BIS_fnc_findNestedElement
- Parameters:
- array: Array - array to explore
- query: Anything - wanted item
- Return Value:
- Array of Numbers - path to the first occurence of query
Examples
- Example 1:
_array = [[1, 2], [3, 4]]; _path = [_array, 3] call BIS_fnc_findNestedElement; // expected result: [1, 0] // ((_array select 1) select 0) == 3
