Node.js Directory Comparison Utility

dir-compare is a Node.js library for comparing the contents and structure of two directories. It provides both synchronous (`compareSync`) and asynchronous (`compare`) comparison methods, supporting various strategies like size, content, and date comparison, along with advanced filtering options including glob patterns and `.gitignore` rules. The current stable version is 5.0.0, with regular updates addressing features, performance, and bug fixes. Key differentiators include its TypeScript support (since v4.0.0), significant performance improvements for large directory structures (e.g., 3x reduced heap usage and 2x faster content comparison since v4.0.0), and flexible extension points for custom comparators and result builders. The command-line interface (CLI) was moved to a separate package, `dir-compare-cli`, in v3.0.0.
