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.

Introduce Variable

When a complex expression or calculation is used multiple times, or when its intermediate result is needed for clarity, this refactoring pulls that expression into a named local variable. This dramatically improves the flow of data within a function, making the code easier to follow without sacrificing performance. It is a key tool for improving local comprehension.
