java script design pattern mediator
" It places the responsibility for maintaining a constraint squarely in the mediator."
what is the meaning of this sentence?
it means that you can more-or-less hijack an existing API, add your own validation to the values accepted by some/all of the API calls, and seamlessly return acceptable values from the original API via the new facade.
this would be in contrast to re-coding the orig API to check constraints inline. if somethings already there are working but not ideal, this is one way to modify it without having to "re-invent the wheel".
im not saying "don't learn the patterns", but don't worry as much about coloring inside the lines as writing a fast and maintainable application.

Agree!!!You can find a Java book which describes this part in detail to read.
