javascript if / else反对的三元运算符 [英] javascript ternary operator opposed to if/else

问题描述

我正在尝试使用javascript的三元运算符语法编写此if / else语句。

I am trying to write this if/else statement using javascript's ternary operator syntax. Is it possible to write this as a ternary operator?

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

我当前的尝试是：

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

推荐答案

您只是错过了赋值语句。因此，最后一个示例将如下所示：

You just miss the assignment statement. So the final example will go like this:

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