Fight!

Popularity

Both Decimal.js and Math.js are popular npm packages for working with mathematical operations. Math.js has a larger user base and is more widely known in the JavaScript community, while Decimal.js is also well-regarded but may have a slightly smaller user base.

Functionality

Decimal.js is specifically designed for precise decimal arithmetic and provides a comprehensive set of methods for working with decimal numbers. It offers features like arbitrary precision, rounding, and formatting. Math.js, on the other hand, is a more general-purpose math library that supports a wide range of mathematical operations, including complex numbers, matrices, and symbolic computations.

Ease of Use

Decimal.js has a simple and intuitive API, making it easy to use for basic decimal arithmetic. It focuses on providing precise decimal calculations without the need for additional configuration. Math.js, being a more comprehensive math library, has a larger API surface and may require more configuration for specific use cases. It offers a powerful and flexible API but may have a steeper learning curve.

Performance

In terms of performance, Decimal.js is optimized for decimal arithmetic and provides efficient algorithms for precise calculations. Math.js, being a more general-purpose math library, may not have the same level of performance for decimal operations. However, for most use cases, the performance difference may not be significant.

Dependencies

Decimal.js has minimal dependencies and is a lightweight package. Math.js, on the other hand, has more dependencies due to its broader functionality. This may be a consideration if you are concerned about the size and complexity of your project's dependencies.

Community and Maintenance

Both Decimal.js and Math.js have active communities and are well-maintained. Math.js has a larger community and a more active development cycle, which means it receives regular updates and bug fixes. Decimal.js, while still maintained, may have a slower release cycle.
