How to merge two hashes?

Question

ruby

There are two hashes:

person1 = { first: "Alex", last: "Go" }
person2 = { first: "Masha", last: "Valeeva" }

Is it possible to change only the value of the last: key using the merge method , or is it better to do it in a smart and simple (Rubive) way?

Answer 1

person1.merge person2.select {|k,_| %i(last somth_else).include? k }
