TIP
关于 UMD 版本的用法请看这里
is.deepEqual
递归检查两个对象是否相等。也支持 Map，Set，ArrayBuffer，Regexp，Date 等等。
import { is } from 'quasar'
const objA = { /* ... */ }
const objB = { /* ... */ }
console.log( is.deepEqual(objA，objB) ) // true or falsecontent_paste
is.object
import { is } from "quasar";
const obj = { some: "value" };
console.log(is.object(obj)); // truecontent_paste
is.date
import { is } from "quasar";
const date = new Date();
console.log(is.date(date)); // true
const now = Date.now();
console.log(is.date(now)); // falsecontent_paste
is.regexp
import { is } from "quasar";
const pattern1 = /\w+/;
console.log(is.regexp(pattern1)); // true
const pattern2 = new RegExp("\\w+");
console.log(is.regexp(pattern2)); // truecontent_paste
is.number
import { is } from "quasar";
const myNumber = 80;
console.log(is.number(myNumber)); // truecontent_paste
