1.背景介绍

Dependency injection (DI) and Inversion of Control (IoC), two fundamental principles in software design, are not easy to understand for developers who have not had a close look at them before. The difficulty lies in the fact that DI and IoC can be applied to many different programming paradigms such as object-oriented programming (OOP), functional programming (FP), procedural programming (PP) or even event-driven programming (EDP).

To help make things clearer for beginners and experts alike, we will present an overview of these concepts based on real-world examples and use cases from OOP, FP, PP and EDP. We'll also discuss how DI and IoC are used in popular frameworks such as Spring Framework and AngularJS.
