Dependency Injection - Introduction

Dependency Injection(DI) is a coding pattern in which a class receives dependencies rather than creating them itself. Some developers and technology mavericks also refer to this as a design pattern.

It's widely used and is often called DI. We will refer to the Dependency Injection system as DI in all our sections.

Here's why we absolutely need DI:

• DI is a software design pattern in which a class receives its dependencies rather than creating the object itself
• DI creates and delivers objects, which are required dynamically just-in-time
• We can consider the injectables as our application's reusable repository
• DI allows independent development of dependency modules for remote development teams.
