lodash用法系列2: 处理对象

Lodash用来操作对象和集合，比Underscore拥有更多的功能和更好的性能。

官网：https://lodash.com/
引用：<script src="//cdnjs.cloudflare.com/ajax/libs/lodash.js/2.4.1/lodash.min.js"></script>
安装：npm install lodash

首先通过npm安装lodash:
npm i --save lodash

在js文件中引用lodash:
var _ = require('lodash');  

import * as _ from "lodash";

判断参数是否是对象 isPlainObject(obj)

function hello(greeting, person){
    if(_.isPlainObject(greeting)){
        person = greeting;
        greeting = 'hi';
    }
    return greeting + person.name;
}

hello('hello',{name:''});
hello({name:''});
