Fight!

Popularity

Both bn.js and mathjs are popular npm packages in the JavaScript community. However, mathjs has a larger user base and is more widely used compared to bn.js.

Functionality

bn.js is a library specifically designed for arbitrary-precision decimal and integer arithmetic. It provides a set of mathematical operations and functions optimized for working with big numbers. mathjs, on the other hand, is a comprehensive mathematics library that offers a wide range of mathematical functions, expressions, and calculations. It supports complex numbers, matrices, units, and more.

Performance

bn.js is highly optimized for performance and is specifically designed for efficient big number calculations. It is known for its fast and accurate arithmetic operations. mathjs, being a more comprehensive library, may have slightly lower performance compared to bn.js when it comes to big number calculations. However, for general mathematical operations, the performance difference may not be significant.

Developer Experience

Both bn.js and mathjs provide a good developer experience. bn.js has a simple and straightforward API, making it easy to use for big number calculations. mathjs offers a more extensive API with a wide range of mathematical functions and expressions, providing flexibility and convenience for complex mathematical operations.

Integration

bn.js is primarily focused on big number arithmetic and may require additional libraries or custom code for other mathematical operations. mathjs, on the other hand, is a comprehensive mathematics library that covers a wide range of mathematical operations, making it suitable for various use cases without the need for additional dependencies.

Community and Maintenance

Both bn.js and mathjs have active communities and are well-maintained. However, mathjs has a larger community and a more active development team, which ensures regular updates, bug fixes, and new features. This makes mathjs a more future-proof choice in terms of community support and maintenance.
