Advanced Techniques: Dependency Injection for the Win!

Why Dependency Injection is the Best:

1. Loose Coupling - Your code is less like a ball of spaghetti

2. Testability - Easy peasy, lemon squeezy!

3. Decoupling - Your codebase becomes less dependent on your sanity

Types of Dependency Injection:Constructor Injection

Method Injection

Provider Injection

Real-World Example:

In a world where cats rule, a dependency injector named Whisker is used to provide a catnip factory:


function CatnipFactory() {
  return new Catnip();
}

const whisker = new DependencyInjector(CatnipFactory);
const catnip = whisker.get('catnip');

Conclusion:

Dependency injection is not just for fancy frameworks. It's for anyone who wants to write maintainable, testable code. Inject your dependencies like a boss!
