How to change Hash values?

Question

I\'d like to replace each value in a hash with value.some_method.

For example, for given a simple hash:

{\"a\" => \"b\",         


        

Answer 1

I do something like this:

new_hash = Hash[*original_hash.collect{|key,value| [key,value + 1]}.flatten]

This provides you with the facilities to transform the key or value via any expression also (and it's non-destructive, of course).
