Add Caching Without Touching Core Logic
Explore how to use the Decorator Pattern to implement a caching mechanism that enhances function performance by storing results for identical inputs. Learn to apply transparent caching to both synchronous and asynchronous functions without altering their core behavior.

Problem statement
Your service calls are getting expensive—each function call hits a simulated API and returns identical data for the same parameters. To reduce redundant work, you’ll implement a caching decorator that remembers results for identical inputs.
This is a classic use of the Decorator Pattern: ...
