Array.join("\n") doesn't work without puts/print/p

[utkarsh2102]

Hi,

Here's one instance:

irb(main):001:0> x = [1,12,123]
irb(main):002:0> x.join("\n")
=> "1\n12\n123"

However, it works fine if used with puts:

irb(main):003:0> x = [1,12,123]
irb(main):004:0> puts x.join("\n")
1
12
123
=> nil

Shouldn't it be working w/o puts/print/p, too?
I'll be happy to raise a PR, too, if you concur with this?
(P.S. I am not sure if that's a bug or a feature)

How you expect it to “work”?

This is by design. In your first example, it's the REPL displaying the actual, understandable representation of an object while the second example sends it to STDIO with no modification. They exist for different purposes and I'd be surprised if there is no distinction between these two.

Thank you, that makes sense! :)
