  • When debugging a function, ensure that the variable you are using is an enumerable object so you can iterate through its properties.

Examples

  • In programming, an array is an enumerable collection that allows you to access each item in a loop.

  • When you realize that any value (e.g., nil, as you suggest) returned by next could be the next value of the enumerable, it becomes clear that it's not possible for it to return a special-case value, since that could then never be in the enumerable.

Morphology

enumerable = enumerate (transparent) = enumerate + able

In programming contexts the adjective signals that a collection can be listed/iterated; the morphological relation to 'enumerate' + '-able' remains direct though the usage is technical.

Etymology

Enumerable comes from the Latin enumerare ('to count out') and is related to number and numeral. So in programming, an enumerable object is one you can list or go through 'one by one', which is why it works with loops and lists.
