javascript if / else反对的三元运算符

Question

我正在尝试使用javascript的三元运算符语法编写此if / else语句。 可以将其写为三元运算符吗？

function changePlayer() {
            if (currentPlayer === playerOne) {
                currentPlayer = playerTwo
            } else {
                currentPlayer = playerOne
            }
        };

我目前的尝试是：

function changePlayer(){
      currentPlayer === playerOne ? playerTwo : playerOne;
}

Answer 1

您只是错过了分配声明。 因此，最后一个示例将如下所示：

function changePlayer(){
      currentPlayer = (currentPlayer === playerOne) ? playerTwo : playerOne;
}

Answer 2

三元运算符的第一个参数是条件：

function changePlayer(){
  currentPlayer = (currentPlayer === playerOne) ? playerTwo : playerOne;
}
