今天用node引入jquery的包来进行遍历数组的时候发现出了一个错误
$.each(arr1, function (i, val) {
^
TypeError: $.each is not a function

[Done] exited with code=1 in 0.643 seconds而引入其他的包就没有问题，网上查了一下才知道要这么做：
var jsdom = require("jsdom");
$ = require("jquery")(jsdom.jsdom().createWindow());
console.lo($);或者
const jsdom = require("jsdom");
const { JSDOM } = jsdom;
const { window } = new JSDOM(`<!DOCTYPE html>`);
const $ = require('jQuery')(window);
console.log($); //测试jquery是否可以正常工作要定义一个jsdom来模拟他的环境这样就好了；
推荐一个工具包 licia很好用的
var bubblesort = require('licia/bubbleSort')
var camelCase = require('licia/camelCase')
console.log(bubblesort([5, 3, 3, 2, 7, 8, 84, 5, 89, 9, 8]));
console.log(camelCase('foo-bar')); // -> fooBar
console.log(camelCase('foo bar')); // -> fooBar
console.log(camelCase('foo_bar')); // -> fooBar
console.log(camelCase('foo.bar')); // -> fooBar结果：
[ 2, 3, 3, 5, 5, 7, 8, 8, 9, 84, 89 ]
fooBar
fooBar
fooBar
fooBar
[Done] exited with code=0 in 0.556 seconds里面封装了很多函数，我们直接调用就可以
