Ruby on Rails Developer Interview Question:

Tell me the difference between ActiveSupport's “HashWithIndifferentAccess” and Ruby's “Hash”?

Submitted by: Muhammad

The “HashWithIndifferentAccess” class will treat symbol keys and string keys as equivalent while the “Hash” class in Ruby will use the stricter = = comparison on keys-an equivalent string key will not retrieve the value for a given symbol key.
