javascript三元运算符反对if / else

Question

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

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

你错过了作业陈述。所以最后的例子将是这样的：

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;
}
