Take a look at the three Tic Tac Toe solutions.

• What did they do well?
  • Good style
  • Helpful comments about complex logic
  • Indentation, Spacing
  • Good variable names & function names
• What could they refactor?
  • Code "smells"
  • Don't Repeat Yourself (DRY)
    • Modularity / Encapsulation / Abstraction
  • Keep it Simple, Stupid (KISS)
    • "Premature optimization is the root of all evil" -- Donald Knuth
  • Separation of Concerns (SoC)
    • Model View Controller (MVC)
      • Model Logic (Data) - e.g. player 1, player 2
      • View Logic (Presentation Logic) - What it looks like
      • Control Logic (Game Logic) - Rules of the game
  • Mixing styles -- Vanilla Javascript DOM Manipulation vs. JQuery DOM Manipulation
  • Overloading Functions
    • Accepts too many parameters (3 or fewer is best!)
    • Does too many things (could be broken down further)
