你可以不用知道的 Angular，深入 DI 叢林
Abstract
Dependency Injection 在台灣常被譯作相依性注入，DI 用得好可以帶來鬆散耦合、可維護以及可測試的程式碼，總地來說，就是個好用的機制。
而如 Angular 這種超大型的前端框架，早早就將這種機制納入核心之中，開箱即可用！
此議程將會深入分析 Angular 原始碼內實作 DI 機制的部分，帶領聽眾進入「你不知道它怎麼運作也無所謂」的實作叢林，了解 Angular DI 機制的設計與巧思。
English Abstract
If you use dependency injection in a good way, it can make your source code decoupled, and become more maintainable and testable.
Angular, a huge frontend framework, has already implemented this mechanism in its core and the mechanism can be used out of the box!
In this section, I will show you how Angular implement its unique DI mechanism which is too much information to you because it won't bother your daily life :)
