Bn.js is a high-performance JavaScript library for arbitrary-precision integer arithmetic. It is commonly used in cryptographic algorithms, big number calculations, and other scenarios where precision and performance are crucial. Bn.js provides a wide range of operations for working with large integers, including addition, subtraction, multiplication, division, and modular arithmetic.
Currency.js is a lightweight JavaScript library for handling currency and money formatting. It provides a simple and intuitive API for working with currency values, including formatting, arithmetic operations, and currency conversion. Currency.js supports various currency formats and allows customization of decimal places, separators, and symbols.
Both bn.js and currency.js are popular npm packages in their respective domains. bn.js is widely used for performing arbitrary precision arithmetic in JavaScript, especially in cryptographic operations. currency.js, on the other hand, is popular for handling currency and monetary values in JavaScript applications.
Functionality
bn.js is specifically designed for performing mathematical operations with arbitrary precision numbers. It provides a comprehensive set of mathematical functions and supports operations like addition, subtraction, multiplication, division, and more. currency.js, on the other hand, focuses on handling currency and monetary values. It provides features like currency conversion, formatting, rounding, and arithmetic operations with currencies.
Use Cases
bn.js is commonly used in cryptographic algorithms, financial calculations, and any scenario where precise arithmetic operations with large numbers are required. currency.js is primarily used in applications that deal with currencies, such as e-commerce platforms, financial applications, and accounting systems.
Performance
bn.js is optimized for performance and provides efficient algorithms for performing arithmetic operations with arbitrary precision numbers. It is designed to handle large numbers efficiently. currency.js, on the other hand, focuses more on providing convenient currency-related functionalities rather than raw performance.
Developer Experience
Both packages have well-documented APIs and are relatively easy to use. bn.js provides a low-level API for performing arithmetic operations with arbitrary precision numbers, which may require some familiarity with mathematical concepts. currency.js, on the other hand, provides a higher-level API specifically tailored for handling currency values, making it easier to work with in currency-related scenarios.
Dependencies
bn.js has minimal dependencies and is a standalone package. It does not rely on any external libraries. currency.js, on the other hand, has a few dependencies, including BigNumber.js, which is used for handling decimal arithmetic.
