ποΈ element_at
Returns the value for the specified key from a key-value pair of a map.
ποΈ map_apply
Applies a [Lambda expression](../Lambda_expression.md) to the keys and values of the original Map and generates a new Map.
ποΈ map_concat
Returns the union of the input maps.
ποΈ map_filter
Filters key-value pairs in a map by applying a Boolean array or a [Lambda expression](../Lambda_expression.md) to each key-value pair.
ποΈ map_from_arrays

ποΈ map_keys
Returns an array of all the keys in the specified map.
ποΈ map_size
Returns the number of elements in a MAP value.
ποΈ map_values
