Tetris randomizers

Tetris randomizers, bueno ver como evoluciono el motor de seleccion de piezas aleatorias en los diferentes tetris:

• random
• random, 1 spot de memoria, 1 nivel de "roll" (no repetidos)
• random, 4 spot de memoria, 4 nivel de "roll" (no repetidos)
• 7 bag (2001+)

function* historyRandomizer() {
  const pieces = ["I", "J", "L", "O", "S", "T", "Z"];
  let history;

  while (true) {
    // First "roll"
    piece = pieces[Math.floor(Math.random() * pieces.length)];
    // Roll is checked against the history
    if (piece === history) {
      piece = pieces[Math.floor(Math.random() * pieces.length)];
    }
    history = piece;
    yield piece;
  }
}
