Examples

Example 1:

_arrayOne set [0, "Hello"];

Example 2:

Append "Bye" as last element to _arrayTwo:

_arrayTwo set [count _arrayTwo, "Bye"];

Example 3:

Replace the last element of _arrayThree with 23:

_arrayThree set [(count _arrayThree) - 1, 23];

Example 4:

Using set with an index that is out of bounds:

private _array = ["A"]; _array set [2, "C"]; // _array is now ["A", nil, "C"] _array set [1, "B"]; // _array is now ["A", "B", "C"]

Example 5:

private _myHashMap = createHashMap; _myHashMap set ["key", "value1", true]; // "key" value is set to "value1" _myHashMap set ["key", "value2", true]; // "key" value is still "value1" as "key" already exists in the hashmap
