In Ruby, we call an object enumerable when it describes a set of items and a method to loop over each of them. The collect() of enumerable is an inbuilt method in Ruby returns a new array with the results of running block once for every element in enum. Related methods.

The Enumerable mixin provides collection classes with several traversal and searching methods, and with the ability to sort. Parameters: The function takes a block according to which partition is to be done. In case no object is given, it return nil for each enum. When running inject on a Hash, the hash is first converted to an array before being passed through..

Parameters for Hash#inject. The class must provide a method each, which yields successive members of the collection. Ruby | Enumerable cycle() function. It returns nil if the loop has finished without getting interrupted. map; select; inject; Enumerable methods work by giving them a block. If Enumerable#max, min, or sort is used, the objects in the collection must also implement a meaningful <=> operator, as these methods rely on an ordering … The cycle() of enumerable is an inbuilt method in Ruby calls block for each element of enum repeatedly the given numbers times or forever if none or nil is given. The partition() of enumerable is an inbuilt method in Ruby returns two arrays, one containing the elements of the enumerable which return true, while the other contains the elements which returns false. chain (>= v2_6_3); chunk; chunk_while; collect; collect_concat Instance methods (62) all?

In that block you tell them what you want to do with every element. The object is repeated every time for each enum. any? It returns an enumerator if no block is passed. If a negative numbers is given or the collection is empty, it does nothing.

Syntax: (r1..r2).collect { |obj| block }. The built-in enumerables get their enumeration features by including the Enumerable module, which provides methods like #include?, #count, #map, #select and #uniq, amongst others.
