当你第一次从其他框架切换到 Angular 是否会有些迷茫，在感叹框架大而全的同时却对其中很多概念不尽了解？近期，为了给不断加入团队的新同学营造一个快速上手的环境，于是把团队的项目代码仔细阅读了一遍，从中挑出了一些在大家提交代码中反复会「犯的错误」，并总结成一系列值得 Angular 新手注意和学习的一些最佳实践。
本分享共分为三个部分，首先会从中后台系统中最经典的部分——响应式表单开始，介绍表单在验证、控制可用性中的一些优化用法和避免死循环的建议，然后第二部分着重从书写规范和编码建议给出了一些用例、以方便大家在日后的开发过程中能有更好的 Code Review 体验，分享的最后一章会就 Angular 项目构建优化给出一些建议。
以下为分享大纲：
- Reactive Forms
- Control Validation
- Infinite Loops
- Control Disabling
- Clean code
- Variable and function names
- Code comments
- Subscribe in templates
- Memory leaks
- Imports with path aliases
- Optimization
- Lazy Loading for main bundle
- Bundle Analyzer
- Lazy Loading for images
- Virtual Scrolling
- Fonts, etc.
注：本分享中提及的虚拟滚动意指 CDK，但未展开分享，感兴趣的同学可以自行搜索相关资料了解。
