The Law of Demeter vs Numerous Dependencies in Code

The Law of Demeter, also known as the principle of least knowledge, is a key concept in object-oriented programming that encourages developers to design code in a way that reduces dependencies between objects. The idea is to minimize the complexity of interactions among various classes and objects, which ultimately simplifies the management and evolution of applications. In practice, applying the Law of Demeter means that an object should have minimal knowledge of another object it collaborates with. This leads to greater modularity and flexibility in the code since changes in one object typically do not affect others. The article provides examples of how following the Law of Demeter can improve code organization and make it easier for other developers to understand. Additionally, it points out the pitfalls that await those who disregard this principle, emphasizing the importance of good programming practices.
