How can you do anything useful without mutable state?

Question

I\'ve been reading a lot of stuff about functional programming lately, and I can understand most of it, but the one thing I just can\'t wrap my head around is stateless codi

Answer 1

Using some creativity and pattern matching, stateless games have been created:

• CSSPlay: Maze Game
• CSSPlay: Maze Game 2
• CSSPlay: Tic-Tac-Toe
• Pure CSS Tic-Tac-Toe
• CSSPlay: Pong
• CSSPlay: Ping-Pong
• CSSPlay: Cops and Robbers
• CSSPlay: Whack-a-Rat
• CSS3 Pong: Insane Things to do with CSS

as well as rolling demos:

• CSSPlay: Random Heroes
• Animated Analog SVG Clock
• Animated SVG Pendulum
• Animated SVG Racers
• CSS3: Making Snow
