What are some alternatives to the Singleton pattern in programming?
Some alternatives to the Singleton pattern include Dependency Injection, Service Locator, and Module pattern. Would you like to know more about any of these?
Can you explain Dependency Injection?
Dependency Injection is a design pattern that allows a class to receive its dependencies from an external source rather than creating them itself. This promotes loose coupling and easier testing.
What about the Service Locator pattern?
The Service Locator pattern provides a central registry where services can be registered and retrieved. It allows for more flexibility but can lead to hidden dependencies.
Are there any downsides to using these alternatives?
Yes, each alternative has its trade-offs. For instance, Dependency Injection can introduce complexity, while Service Locator can obscure dependencies, making the code harder to understand.
