alias :aliased_map :map

#destructure(num_elems) ⇒ Array<Object>

Destructuring for the array class. If the array is being matched against two patterns the destructuring of the array will be the first element and then an array containing the rest of the values. If there are three patterns the destructuring of the array will be the first and second elements, and then an array containing the remainder of the values.

Parameters:

  • num_elems (Fixnum) —

    Number of sub-pattern elements

Returns:

def destructure(num_elems)
	[*self.first(num_elems - 1), self[(num_elems - 1)..-1]]
end

#map(method = nil, &block) ⇒ Array<Object>

Parameters:

  • method (Symbol) (defaults to: nil) —

    Method to be invoked on the array elements.

  • block (Proc) —

    Normal Array#each block.
