CORE DEFINITION

A design pattern that reduces memory usage by sharing as much data as possible. It divides object state into intrinsic state (shareable) and extrinsic state (non-shareable).

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Optimize resource allocation. When dealing with a large number of similar tasks or objects, extract the invariant 'common denominator' for reuse, and handle only the differences separately to reduce system load.

anchor

Anchor fast decisions

Reduce memory/resource usage by sharing the common parts of a large number of fine-grained objects, replacing repetition with sharing.
