Method: Array#traverse

Defined in:
lib/core/facets/array/traverse.rb

#traverse(&block) ⇒ Object

Construct a new array created by traversing the array and its sub-arrays, executing the given block on the elements.

Examples

h = ["A", "B", ["X", "Y"]]
g = h.traverse{ |e| e.downcase }
g  #=> ["a", "b", ["x", "y"]]

This is the same as recursive.map and will likely be deprecated in the future because of it.

Returns new array. [Array]
