Strategy

The Strategy pattern allows an object, known as the context, to adapt its behavior by delegating specific parts of its logic to interchangeable objects called strategies. The context defines the common structure of an algorithm, while each strategy encapsulates a variation of its mutable aspects. This approach enables the context to modify its behavior dynamically based on factors such as input values, system configurations, or user preferences.

Here’s a real-life story (from Mario) about how the Strategy pattern helped me optimize a performance-critical operation. While this example isn’t directly related to Node.js, it demonstrates just how fundamental and universal this pattern is.

Years ago, I was working on a 3D game engine as a personal project. Game engines are notoriously resource-intensive, where every optimization matters to ensure smooth performance. A key component of 3D rendering is matrix multiplication, and at the time (early...
