Im trying to get a random object from an array, and add it to a string.
我试图从数组中获取一个随机对象，并将其添加到字符串中。
var input = ['1', '2', '3']
console.log(input[Math.floor(Math.random() * input.length)] + " some text")
However, when you run this, it does nothing. If you label this post as a duplicate, please know that the question is not asking how to randomize an array, my question is how do I add an object from an array, and add it to a string.
但是，当你运行它时，它什么都不做。如果你把这篇文章标记为重复，请知道问题不是询问如何随机化一个数组，我的问题是如何从数组添加一个对象，并将其添加到一个字符串。

Your are trying to add a string from array instead of object. And your code works fine, try this.
您正在尝试从数组而不是对象添加字符串。你的代码工作正常，试试这个。
"use strict";
let input = ['1', '2', '3'];
let amount = input.length;
console.log(input[Math.floor(Math.random() * amount)] + " some text");#1
