description Overview

JavaScript Module System Migration (CommonJS to ESM)

Migrating large JavaScript codebases from CommonJS (`require()`) to native ES Modules (`import`/`export`) is a massive refactoring effort. This change affects how dependencies are resolved, how scope is managed, and how bundlers operate. It is critical for adopting modern tooling and ensuring compatibility with modern JavaScript runtimes and build pipelines.

Change Signature

When an API contract must changesuch as adding a required parameter, changing a return type, or renaming an argumentthis tool manages the ripple effect. It updates every single call site that uses the method, prompting the developer to handle the new signature, thereby managing backward compatibility gracefully across the codebase.
