each_index

ary.each_index { |index| block } â ary
ary.each_index â Enumerator

Instance Public methods

Same as #each, but passes the index of the element instead of the element itself.

An Enumerator is returned if no block is given.

a = [ "a", "b", "c" ]
a.each_index {|x| print x, " -- " }

produces:

0 -- 1 -- 2 --
