deep-equal is a Node.js module for performing deep equality comparisons between JavaScript values. Unlike strict equality (===), it recursively compares the contents of objects, arrays, dates, and other complex data types. This allows for checking if two independent data structures contain the same values, regardless of their memory addresses. deep-equal handles circular references gracefully and supports custom equality tests for specific types, making it a versatile tool for testing, data validation, and more. It provides a reliable way to determine whether two values are logically equivalent.
The deep-equal npm package has seen inconsistent release frequency since its initial release in February 2012. Releases were more frequent in 2013-2015 and 2019-2020, with periods of no releases in between. The package had consistent releases in 2023, but has had no releases so far in 2024 or 2025, as of August 27, 2025.
Deep-equal npm package downloads show strong performance, fluctuating between 80-104 million from March 2024 to July 2025. A notable spike occurred in October 2024 (102M) and June 2025 (103M). August 2025 downloads (69M) are incomplete and lower, as the month is still in progress.
