Get a Random Array Item with JavaScript

JavaScript Arrays are probably my favorite primitive in JavaScript. You can do all sorts of awesome things with arrays: get unique values, clone them, empty them, etc. What about getting a random value from an array?

为了从一个阵列中获取一个随机项目,你可使用<条码>。

const arr = [
    "one",
    "two",
    "three",
    "four",
    "tell",
    "me",
    "that",
    "you",
    "love",
    "me",
    "more"
];
const random1 = arr[(Math.floor(Math.random() * (arr.length)))]
const random2 = arr[(Math.floor(Math.random() * (arr.length)))]
const random3 = arr[(Math.floor(Math.random() * (arr.length)))]
const random4 = arr[(Math.floor(Math.random() * (arr.length)))]

console.log(random1, random2, random3, random4)
// tell one more two

至于你需要从一个阵列中随机取值,这取决于您的个人应用。 然而,我很想知道,你很容易获得随机价值。 是否应当有<条码>。
