Forum: Ruby Confusion with Enum#with_index

I was playing to understand the method "Enum#with_index" with the below
code:

===================================================
irb(main):024:0> xs = ['a', 'b', 'c']
=> ["a", "b", "c"]
irb(main):025:0> xs.to_enum.with_index(2)
=> #<Enumerator: #<Enumerator: ["a", "b", "c"]:each>:with_index(2)>

====================================================

irb(main):014:0> to_three = Enumerator.new do |y|
irb(main):015:1*  3.times do |x|
irb(main):016:2* y<<x
irb(main):017:2> end
irb(main):018:1> end
=> #<Enumerator: #<Enumerator::Generator:0x2193ca8>:each>
irb(main):027:0> to_three.with_index(2)
=> #<Enumerator: #<Enumerator:
#<Enumerator::Generator:0x2193ca8>:each>:with_ind
ex(2)>

====================================================

Couldn't understand the output of "to_three.with_index(2)" .

Could anyone help me?

"Couldn't understand..." is not a particularly clear way to
ask a question.

What did you expect? What puzzled you?

The "output" is only the string representation of the enumerator
object that you created. But you haven't "done" anything with it.

???? That's your input.
