## Description

Microdiff is a utility library for calculating structural differences between two JavaScript objects or arrays. It identifies additions, removals, and modifications by performing a deep comparison of nested data structures, providing a granular list of changes between object states.

The library is built with a zero-dependency implementation that relies exclusively on native language primitives to maintain a minimal memory footprint. It includes built-in circular reference handling, which tracks object identities during traversal to prevent infinite loops when processing self-referencing data structures.

These capabilities support tasks such as object state synchronization and structural validation within strongly typed environments. The library is designed to function as a lightweight tool for managing complex data comparisons in both web and server-side applications.
