使用vue重构ToDoList—最简单的待办事项列表

你们好，我是一个刚入门前端的一个小白，但愿各位大佬们可以对小的多多指导，我先作一下自我介绍吧。我叫王小辉，我大学的专业是播音主持，为何选择学习前端呢，这就跟我大学最后一年跟几个小伙伴一块儿创业开始提及，其实也不能彻底说成创业，其实就是大学期间认识的几个小伙伴想一块儿作一些喜欢的事情，那是18年年初，当时小程序市场起步，市场上大大小小的小程序公司如雨后春笋冒出来，当时咱们以为这个小程序是一个市场，而且能够经过大学生创业这个方式获取到一些资源。个人另两个小伙伴分别是商学院和艺术设计学院的，咱们当时没有一我的懂得技术，因此咱们就了解到了，一些大的互联网公司作的小程序能够代理，能够开代理商后台的，咱们当时拿着三千以大学生创业的身份跟广州的一家小程序公司谈，最后谈了下来，基本一个模版都在300-1000左右的拿货价，接下来咱们就开始了漫长的推广过程，恰好当时赶到暑假，临时招募学校里的几位同窗加入咱们，公司的运营总共持续了5个月左右，总共谈下2位代理，8个客户，共计收到打款十多万。感受本身扯的有点远了，继续说回为何想要学习编程，就是由于在咱们业务的过程当中遇到了不少的难题，模版的功能是固定的，客户的需求没法知足，给当时的咱们形成不少的困扰，因此当时就萌生了这个想法，当时也尝试着学习一些基础的页面的东西，尝试去知足客户需求，可是对于一个什么都不动的文科生，实在是太难了。可是前端时间由于疫情因此决心转变一下，当时也是考虑好久，对前端也比较感兴趣。其余废话就不说了，最近学到vue，作了一个做业，在这里分享出来，但愿大佬指点一下，哪里须要改进，请不吝赐教。javascript

先来分享一下已经打包上线的demo

ToDoList-代办事项列表

为了练习数据流，我总共分红了三个组件
其实最后两个组件逻辑类似，实际上是能够和在一块儿的，这样能够节省不少代码段
下面这个Home是主组件vue
