Description: Mutability refers to the ability of an object to change its state after it has been created. In the context of programming and code review, this concept is fundamental as it influences how data is managed and software structures are designed. A mutable object can be modified without the need to create a new instance, allowing for greater flexibility and efficiency in data manipulation. However, this characteristic can also introduce complexities, such as concurrency issues and unintended side effects, which can complicate debugging and code maintenance. Therefore, it is crucial for developers to understand the implications of mutability when writing and reviewing code, ensuring that appropriate practices are implemented to handle mutable objects safely and effectively. Mutability contrasts with immutability, where an object, once created, cannot be altered. This distinction is key in many programming languages and design paradigms, affecting how applications are structured and how object states are managed.
