Array extensions examples

// easy examples with a numeric array
_data = [1,2,3,4,5,6,7,8,9];

// filter
_fnc = { _this >= 5 };
[_data, _fnc] call AEX_filter; // [5,6,7,8,9]
[_data, { _this < 4 }] call AEX_filter; // [1,2,3]
[_data, { _this > 2 and _this < 8 }] call AEX_filter; // [3,4,5,6,7]
[_data, { _this mod 2 == 0 }] call AEX_filter; // [2,4,6,8]

// map
[_data, { _this * 2 }] call AEX_map; // [2,4,6,8,10,12,14,16,18]
[_data, { str _this }] call AEX_map; // ["1","2","3","4","5","6","7","8","9"]

// reduce
[_data, { (_this select 0) + (_this select 1) }] call AEX_reduce; // 45

// combination of filter and reduce
[[_data, { _this <= 5 }] call AEX_filter, { (_this select 0) * (_this select 1) }] call AEX_reduce; // 120


// real ArmA examples
