overall review score: 4.5
⭐⭐⭐⭐⭐

The singleton pattern is a software design pattern that restricts the instantiation of a class to one object, providing a global point of access to that instance.
Key Features
- Restricts instantiation
- Global point of access
- Can be lazily initialized
Pros
- Ensures only one instance of a class exists
- Provides a global access point to the instance
- Allows lazy initialization for better performance
Cons
- Can lead to tight coupling and dependencies in the codebase
- Singleton pattern can also be seen as an anti-pattern in some cases
