javascript - 为什么我的数组中的项目不显示在单独的行中？

Question

我想使数组中的每一项都显示在不同的行中，但我的“\n”不起作用。我把它放错地方了吗？我试过把它放在其他地方，但似乎没有什么不同。我的函数目标是遍历数组。

var employees = [];
employees[0] = "Zak";
employees[1] = "Jessica";
employees[2] = "Mark";
employees[3] = "Fred";
employees[4] = "Sally";

var showEmployee = function (names) {
    'use strict';
    showEmployee = employees;
    return names;
};

showEmployee(employees);
window.console.log(showEmployee + "\n");

你在数组的末尾添加了一个换行符，你需要在数组中的每个元素之间添加它(使用连接)

var employees = [];
employees[0] = "Zak";
employees[1] = "Jessica";
employees[2] = "Mark";
employees[3] = "Fred";
employees[4] = "Sally";

var showEmployee = function (names) {
    'use strict';
    showEmployee = employees;
    return names;
};

showEmployee(employees);
window.console.log(showEmployee.join("\n"));
