Question

Hash.each returns an array [key, value],
but if I want a hash?

Example: {:key => value }

Answer 1

I’m assuming you meant “yields” where you said “return” because Hash#each already returns a hash (the receiver).

To answer your question: If you need a hash with the key and the value you can just create one. Like this:

hash.each do |key, value|
  kv_hash = {key => value}
  do_something_with(kv_hash)
end

There is no alternative each method that yields hashs, so the above is the best you can do.
