Separation of Concern

Excerpt from Oghenevewede Emeni’s “Separation of Concerns in Node.js” (October 19, 2022)¹:

• Separation of concerns is [an] architecture that ensures code readability, easy refactoring, and good code collaboration.

• Using the separation of concerns principle, you can ensure that the final system is stable and maintainable.

• The principle of separation of concerns ensures that components are not duplicated, making the system easier to maintain and refactor.

• The separation of concerns principle holds that business logic should be kept separate from controllers. This simplifies the development of thin controllers and the writing of tests.

• Separation of Concerns principle aids in code reusability. This reduces maintenance costs and time by making it simple to determine where a fault is coming from and how is isolate it from the entire system.
