Map Containers

Objects with keys that index to values, where keys need not be integers

Store data values in aMapobject, which is a data structure that associates each value with a corresponding key. AMapobject is similar to a dictionary or associative array in that you can use keys to retrieve values from it. Keys can be numbers or text, providing more flexibility for data access than array indices.
