#each(&block) ⇒ Object Also known as: each_pair

Calls the given block for each element of self and pass the key and value of each element.

call-seq:

hsh.each      {| key, value | block } -> hsh
hsh.each_pair {| key, value | block } -> hsh
hsh.each                              -> an_enumerator
hsh.each_pair                         -> an_enumerator

If no block is given, an enumerator is returned instead.

h = { "a" => 100, "b" => 200 }
h.each {|key, value| puts "#{key} is #{value}" }
