Command Pattern

With the Command Pattern, we can decouple objects that execute a certain task from the object that calls the method.

Let's say we have an online food delivery platform. Users can place, track, and cancel orders.

When to Use

Use this when you need to decouple the object invoking an operation from the object performing it

This is helpful when commands need a certain lifespan or should be queued and executed at specific times

When NOT to Use

For simple one-off operations that don't need undo/redo, queuing, or logging

When direct function calls are clear enough and the extra abstraction adds complexity without benefit

When the system has few operations and the command infrastructure would be over-engineering
