filter()
public
Returns a new hash consisting of entries for which the block returns true.
If no block is given, an enumerator is returned instead.
h = { "a" => 100, "b" => 200, "c" => 300 } h.select {|k,v| k > "a"} #=> {"b" => 200, "c" => 300} h.select {|k,v| v < 200} #=> {"a" => 100}
Hash#filter is an alias for Hash#select.
