Abstraction

Abstraction hides complex implementation details behind a simple, well-defined interface. Like how a car's steering wheel abstracts away the power steering pump, rack and pinion, and hydraulic lines — you just turn the wheel. Good abstractions let callers focus on what to do, not how it is done, reducing cognitive load and coupling.

Use Cases

•Providing a simple send() method that hides SMTP configuration, retries, and templating
•Abstracting database queries behind a repository with findById() and save() methods
•Wrapping complex API authentication flows behind a single getClient() call
•Hiding file system, cloud storage, or CDN details behind a unified Storage interface
