高性能的js第三方库——lodash、 Underscore、async、md5及moment

import * as _ from 'lodash'
import * as _s from 'underscore'//数组去重对比
_.uniq([1,1,3])
// => [1,3]_s.uniq([1, 2, 1, 4, 1, 3]);
=> [1, 2, 4, 3]

import * as _async from 'async'
import * as _moment from 'moment'
import * as _md5 from 'md5'shunXuAsync(){
// 异步 顺序执行
let task1 = function (callback) { console.log("task1");
callback(null, "task1")
} let task2 = function (callback) { console.log("task2");
callback(null, "task2")
// callback("err","task2") // null改为err ,如果中途发生错误,则将错误传递到回调函数,并停止执行后面的函数

var objects = [{ 'a': 1 }, { 'b': 2 }];var shallow = _.clone(objects);

_.isEmpty(null);
// => true_.isEmpty(true);
// => true_.isEmpty(1);
// => true_.isEmpty([1, 2, 3]);
// => false_.isEmpty({ 'a': 1 });
// => false//7.多维数组合并为一维数组

//8.根据某个字段排序

const users = [
{ 'user': 'fred', 'age': 48 },
{ 'user': 'barney', 'age': 34 },
{ 'user': 'fred', 'age': 42 },
{ 'user': 'barney', 'age': 36 }
];

// 以 `user` 升序排序 再 以 `age` 降序排序。
_.orderBy(users, ['user', 'age'], ['asc', 'desc']);

// 9 .简单数组的排序

_.sortBy(arr, function(item) {
return item.createTime;
});

_.sortBy(arr, function(item) {
return -item.createTime;
});

// 10.判断是否有重复

_.uniq([2, 1, 2])
// => [2, 1]

if(_.uniq(arr) = arr.lengh){ // 判断去重后的数组长度

}
