从 Node Inquirer 的复选框创建的数组中删除逗号

Removing commas from Array created with checkbox from Node Inquirer

我有以下询问者提示,据我所知returns 一个字符串数组:

 {name: "food",
        message:"choose your favorite ➝ ",
        type: "checkbox",
        choices: ["option1", "option2", "option3", "option4", "option5", "option6"],
        when: function(answers) {
          return answers.client;
        },
        validate: function(choices) {
            return choices.length <= 3 ? true : "Please select at least 3 choices";
        }

然后我想打印答案如下:

let foods = answers.food ? "You chose the following: \n " + answers.food.map(option => "• " + option + "\n") : "";

希望得到类似的东西:

您选择了以下选项: • 选项1 • 选项2 • 选项 3

相反,我得到的是这样的东西:

• 选项 1 ,• 选项2 ,• 选项3

有人知道如何删除那些烦人的逗号吗?

您正在将一个数组连接到一个字符串,JS 通过调用带有参数 ,Array#join 来处理这个问题。所以考虑到这一点,你可以做 let foods = answers.food ? "You chose the following: \n " + answers.food.map(option => "• " + option + "\n").join('') : "";
