Big.js is a JavaScript library for arbitrary-precision arithmetic, allowing precise handling of large numbers without losing accuracy due to JavaScript's limitations with floating-point arithmetic. It provides methods for performing arithmetic operations like addition, subtraction, multiplication, and division on numbers with arbitrary precision. Big.js is particularly useful for financial calculations, cryptography, and any scenario where precision is crucial.
Currency.js is a lightweight JavaScript library for handling currency and money formatting, conversion, and arithmetic operations. It provides a simple and intuitive API for working with monetary values, allowing developers to easily format currencies, perform calculations with automatic precision handling, and convert between different currencies.
Both Big.js and Currency.js are JavaScript libraries that provide functionality for working with numbers. Big.js is primarily focused on arbitrary-precision decimal arithmetic, allowing precise calculations with large numbers. Currency.js, on the other hand, is specifically designed for working with currency values, providing features like formatting, conversion, and arithmetic operations with currencies.
Popularity
Big.js has been around for a longer time and has gained a significant following in the JavaScript community. It is widely used in projects that require precise decimal arithmetic. Currency.js, although less popular, has also gained some popularity, especially in projects that deal with currency-related calculations.
Ease of Use
Big.js provides a simple and straightforward API for performing arithmetic operations with arbitrary-precision decimal numbers. It is easy to integrate into existing projects and has good documentation. Currency.js, on the other hand, is specifically tailored for working with currencies, providing intuitive methods for formatting, converting, and manipulating currency values.
Performance
Big.js is optimized for precise decimal arithmetic and provides accurate results even with large numbers. However, due to its focus on precision, it may be slower compared to other libraries when performing arithmetic operations. Currency.js is also performant but is optimized for currency-related calculations, which may be faster in scenarios that involve currency conversions and formatting.
Dependencies
Big.js has no external dependencies, making it lightweight and easy to include in projects. Currency.js, on the other hand, has a few dependencies, including Big.js itself, which is used for handling decimal arithmetic. This may increase the overall bundle size of projects that use Currency.js.
Community Support
Both Big.js and Currency.js have active communities and are actively maintained. Big.js has been around for a longer time and has a larger user base, which means it has more community support and resources available. Currency.js, although less popular, still has an active community and provides support for its users.
