Hi,
I have one basic question to ask regarding Hash key. Follow the below :
"foo".object_id # => 72994000
"foo".object_id # => 72993390
{"foo" =>2,"foo" =>3} # => {"foo"=>3}
I do know that Hash don't allow duplicate keys. But I would like to by
which method hash check if any duplicate key present into it or not? As
I can see "foo" have different `object_id`,which is expected. But in
case of Hash key how this two different objects "foo" is treated as same
object?
