Answer / ash
Singleton - single instance of the class will be used. Many
uses.
facade - simplifying interface(s) into simple interface.
Used in application or presentation layer as api or for
wrapping external third-party api/resource
Handle - one method interface with one "action" argument.
Other arguments can be passed as list for "action". Used
when we dont know upfront which methods we would support and
dont want clients to recompile. Somewhat similar to command
pattern
