Cohesion, Coupling, and Separation of Concerns
Master three foundational software design properties that determine whether code stays maintainable: high cohesion, low coupling, and clear separation of concerns.
Why These Properties Matter
Under clean code and SOLID lie three deeper design properties: cohesion, coupling, and separation of concerns. They explain why the rules work.
What is Cohesion
Cohesion measures how well a module’s responsibilities belong together. High cohesion = one well-defined job; low cohesion = a grab-bag of unrelated methods.
