吉凶以情迁
前几个月研究了低代码很快给公司完成了一个简单的管理后台，当然，后端接口自己写的。前端全部自动化，

学了很多 但是长时间没弄，还是会遗忘，现在已经忘得完全不知道是怎么回事了，
我学过的东西很少有坚持持续的去回顾的。
想到了著名的费曼学习法，或许我只知道学试试新鲜感，却没有反复的去用，是导致我只能刚刚入门这样子，我想，我还是需要做点笔记的，虽然不会很详细，但是或许可以让我联想起来我曾经学过的东西 再次捡起来。。

很多东西在文档里有，这里只记录一些技巧
开发项目采用vscode 结合 preview预览插件 可以实时预览更新提高效率

just html preview
Live Preview
上面的index.html是整个的入口，
里面 api: '/pages/site.json' 涵盖了 整个界面的定义显示，
而这些文件则全是静态的，不是调用的接口。

而这是我曾经的笔记
