Replace a hash with another key-value pair
counties = { "Three" => 3, "Five" => 5 } temp = {"Three" => 3 } counties.replace( temp )
Replace all of the pairs in h with those from another hash
h = {} # Start with an empty hash h[:a] = 1 # Map :a=>1. h is now {:a=>1} h.store(:b,2) # More verbose: h is now {:a=>1, :b=>2} h.replace({1=>:a, 2=>;b} # h is now equal to the argument hash
Replace hash with a constant
counties = { "Three" => 3, "Five" => 5 } counties.replace( { "Three" => 3 } )
