script.js: Strat button => game_start() => getPlayerChoice(e) => playRound() => check_Winner()
promblems:
- 分數到5時,直接跳回game_start()導致無法顯示5分
sol:
- create another function to show the game result and disable the three buttons until press 'start' button. (disabble_listener())
物件: hint : 輸贏提示 points : 分數 three_btn : start
