hsh.each_pair {| key, value | block } â hsh
hsh.each_pair â an_enumerator

Instance Public methods

Calls block once for each key in hsh, passing the key-value pair as parameters.

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

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

produces:

a is 100
b is 200
