Inversion of control is a big and complicated concept that even some Senior developers struggle to fully understand. But I'll do my best to explain it in the best possible way for you to understand, teach and see its application.
When all have a home of our own. We need water and power. We have two options we create power ourselves and make a borehole or we outsource to another body only responsibility is that and does it well.
In the case of power we rely on Power Holding company of Nigeria and for water we rely on Nigeria water cooperation to provide that for us.
In the example, the control of providing power and water is moved to third-party organizations, which are responsible for generating power and providing water. This allows the homeowners to focus on their own needs without worrying about the technical details of how power or water is generated or distributed
That's kind of inversion of control. You're the one who wants something, but you're not the one doing all the work to get it. You're relying on someone or an organization else to help you out.
In software development, inversion of control (IoC) is a design pattern that allows different parts of a program to work together in a more flexible and maintainable way. It's a way of designing software so that instead of one part of the program being responsible for everything, different parts can work together in a more decentralized way.
IoC works by inverting the usual control flow between different parts of a program. In a traditional program, each part of the program is responsible for calling other parts of the program when it needs them. This can lead to tight coupling between different parts of the program, which can make it hard to change or replace parts of the program without affecting other parts.
With IoC, the control flow is inverted so that the parts of the program that are responsible for providing services or resources (known as "providers") are called by the parts of the program that need those services or resources (known as "consumers"). This means that the providers don't need to know about the consumers, which makes the program more modular and easier to change or replace.
In computer programming, inversion of control is a way of designing programs so that different parts of the program can work together without any one part having to do everything by itself. Instead of one part of the program doing everything, it asks other parts of the program to help out.
So just like how you rely on mommy or daddy to help you get what you want sometimes, different parts of a program rely on each other to get things done. And that's inversion of control!
There are many different ways to implement IoC in software development, such as using dependency injection, service locators, or the observer pattern. The specific implementation depends on the programming language and framework being used.
Overall, inversion of control is a powerful design pattern that can help make software development more flexible, maintainable, and modular. By inverting the control flow between different parts of a program, IoC can help reduce tight coupling and make it easier to change or replace different parts of the program as needed.
