Most developers have heard of the original “Design Patterns” book.

Many have even read it.

Some patterns, like Factory and Singleton, have become commonly known. Beyond these, and beyond the original catalogue written by the Gang of Four, there are many other patterns that can be invaluable in the right situation.

  • Null Object
  • Command
  • Emancipated Objects
  • Proposal
  • State
