导出函数

helper.js

function generateList(count, closure) {

const list = [];

let last = {};

let current = null;

for (let i = 0; i < count; ++i) {

current = closure(i, deepCopy(last));

current = Array.isArray(current) ? current : [current]

list.push(...(deepCopy(current)));

last = deepCopy(current);

}

return list;

}

module.exports = {

sleep,

between,

toPx,

deepCopy,

generateList,

}

使用：

import {generateList,sleep} from '@/common/helper.js'

sleep(100);

导出类对象

index.js

import {generateList,sleep} from '@/common/helper.js'

class Data {

async messages() {

await sleep(300);

const list =generateList(2, () => {

return [
