Both BigNumber.js and Money are popular npm packages in their respective domains. BigNumber.js has been around for longer and has a larger user base, while Money is also well-regarded and widely used for handling monetary values in JavaScript applications.


BigNumber.js is a library specifically designed for arbitrary-precision arithmetic, making it suitable for handling large numbers and precise calculations. It provides a comprehensive set of mathematical operations and supports various number formats. Money, on the other hand, focuses on handling currencies and provides features such as currency conversion, formatting, and rounding. It has built-in support for currency symbols, codes, and exchange rates.

Ease of Use

Both packages are relatively easy to use. BigNumber.js offers a straightforward API for performing mathematical operations on arbitrary-precision numbers. Money provides a convenient API for working with currencies, including features like formatting, parsing, and conversion. The choice between them depends on the specific requirements of your project and whether you need general-purpose arbitrary-precision arithmetic or currency-specific functionalities.


In terms of performance, BigNumber.js has a reputation for being fast and efficient in handling large numbers, thanks to its optimized algorithms and data structures. Money, being primarily focused on currency-related operations, may have slightly lower performance when dealing with very large numbers. However, for most use cases related to currency calculations, the performance difference would be negligible.


Both BigNumber.js and Money have well-maintained documentation that includes examples, guides, and API references. BigNumber.js has a more extensive and comprehensive documentation due to its broader range of mathematical operations. Money's documentation is specifically tailored towards currency-related functionalities, providing clear explanations and examples for handling currencies in JavaScript.

Community and Maintenance

Both packages are actively maintained by their respective communities. BigNumber.js has a larger user base and a longer history, which means it has a more mature community, frequent updates, and a solid ecosystem. Money, while relatively newer, is also maintained and updated regularly to keep up with the evolving needs of currency handling in JavaScript applications.
