An array in NXSL is actually an ordered map. A map is a type that associates ''values'' to ''keys''. This type is optimized for several different uses; it can be treated as an array, list (vector), hash table (an implementation of a map), dictionary, collection, stack, queue, and probably more. As array values can be other arrays | An array in NXSL is actually an ordered map. A map is a type that associates ''values'' to ''keys''.

A ''key'' must be a non-negative integer. When an array is created, its size is not specified and its map can have empty spots in it. For example, an array can have a element with a ''0'' key and an element with ''4'' key and no keys in-between. Attempting to access an array key which has not been defined is the same as accessing any other undefined variable: the result will be <tt>NULL</tt>. | |||
