获取随机字符串

原生生成随机串

let uuid = window.crypto.randomUUID();
console.log(uuid); // 例如 "36b8f84d-df4e-4d49-b662-bcde71a8764f"

项目中用 uuid

import { v4 as uuidv4 } from "uuid";
uuidv4(); // ⇨ '9b1deb4d-3b7d-4bad-9bdd-2b0d7b3dcb6d'

生成 uuid

const uuid = (a) =>
  a
    ? (a ^ ((Math.random() * 16) >> (a / 4))).toString(16)
    : ([1e7] + -1e3 + -4e3 + -8e3 + -1e11).replace(/[018]/g, uuid);
