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.

Extract Constant

This tool identifies literal values (like '3.14159' or 'MAX_RETRIES') used repeatedly throughout the code. It extracts these 'magic numbers' into a dedicated, named constant field or variable. This centralizes configuration, making global changes trivial and preventing inconsistencies across the codebase.
