Singletons

Singletons are a design pattern in object-oriented programming that restricts the instantiation of a class to only one object. This ensures that only one instance of the class can exist in the entire program, and it is commonly used to control global access to a resource or provide a central point for managing application state.

Why Learn Singletons?

There are several benefits to using the Singleton design pattern:

• Global Access: Singletons provide a single, globally accessible point of access to shared resources or services that can be used throughout the application.
• Controlled Instantiation: By limiting the instantiation to a single object, Singletons prevent multiple instances of the same class from being created, ensuring consistency and avoiding resource conflicts.
• State Management: Singletons can be used to manage application state by providing a centralized location for storing and accessing global data.
• Efficient Memory Usage: By restricting the number of instances to one, Singletons optimize memory usage by eliminating the overhead of creating and maintaining multiple objects.
