Concordance version 0.4.0, released on May 3, 2017, is a JavaScript utility designed for comparing, formatting, diffing, and creating snapshots of JavaScript values. It is the first stable version after a period of alpha releases. The package aims to provide developers with robust tools for understanding differences between JavaScript objects, arrays, and other data structures, making it valuable for testing, debugging, and serialization scenarios.
This version depends on several core libraries, including esutils for ECMAScript language utilities, fast-diff for efficient text difference calculation, and lodash utilities like clonedeep, flattendeep, and merge for data manipulation and deep cloning. It also relies on well-known-symbols for consistent handling of JavaScript symbols.
For development, this version incorporates a comprehensive suite of tools for testing and quality assurance. These include ava for test running, @novemberborn/as-i-preach for code style enforcement, benchmark for performance testing, chalk for colorful console output, codecov for code coverage reporting, left-pad for string padding, lodash.isequal for deep equality checks, nyc for code coverage analysis, and pretty-format for readable object serialization in tests. The choice of pretty-format suggests a strong focus on user-friendly and informative test output, highlighting the package's usability in debugging complex data structures. This focus on comprehensive testing and clear output indicates a commitment to reliability. Concordance is licensed under ISC and maintained in a GitHub repository.
