hsh[key] = value â value Instance Public methods Element Assignment Associates the value given by value with the key given by key. h = { "a" => 100, "b" => 200 } h["a"] = 9 h["c"] = 4 h #=> {"a"=>9, "b"=>200, "c"=>4} key should not have its value changed while it is in use as a key (an unfrozen String passed as a key will be duplicated and frozen). a = "a" b = "b".freeze h = { a => 100, b => 200 } h.key(100).equal? a #=> false h.key(200).equal?
