多组件遇到的问题
所有组件都写到了一起，耦合性太强，程序容易起冲突，具体如下
全局定义 强制要求每个 component 中的命名不得重复
字符串模板 缺乏语法高亮，在HTML有多行的时候，需要用到丑陋的 \
不支持css 意味着当HTML 和 JavaScript 组件化时，css 明显被遗漏
没有构建步骤，限制只能使用 HTML 和 Ess JavaScript ，而不能使用预处理器，如 Pug 和 Babel
webpack 工具
四个核心概念：
入口（entry），出口（output），模块加载（loader），插件（plugins）
webpack 基础使用
npm init
npm install --save-dev [email protected]
webpack entry.js bundle.js; // webpack entry.js -o bundle.js 备注 -o ， 如果bundle.js文件不存在-o才生效
----------------------
webpack entry.js -o bundle.js
Hash: f7ca9a08c9bf6c4a30f6
Version: webpack 4.42.0
Time: 303ms
Built at: 2021-02-01 16:17:30
Asset Size Chunks Chunk Names
bundle.js 930 bytes 0 [emitted] main

WARNING in configuration
The 'mode' option has not been set, webpack will fallback to 'production' for this value. Set 'mode' option to 'development' or 'production' to enable defaults for each environment.
You can also set it to 'none' to disable any default behavior. Learn more: https://webpack.js.org/configuration/mode/
