Both Currency.js and Decimal.js are popular npm packages for handling currency and decimal calculations. Currency.js has been around for longer and has gained popularity for its simplicity and ease of use. Decimal.js, on the other hand, is also well-known and widely used for its precision and extensive mathematical operations.
Currency.js focuses specifically on currency handling and provides features like currency conversion, formatting, and arithmetic operations. It offers built-in support for formatting currencies based on different locales. Decimal.js, on the other hand, is a more general-purpose decimal math library that provides extensive mathematical operations, precision control, and arbitrary-precision arithmetic for handling decimal numbers.
Decimal.js is known for its high precision and accuracy in decimal calculations. It allows you to specify the desired precision and rounding methods for mathematical operations. Currency.js provides a fixed precision of 2 decimal places by default, which is suitable for most currency operations, but may not be suitable for all use cases that require high precision.
Ease of Use
Currency.js has a simple and intuitive API that is easy to grasp and use. It provides a fluent syntax for chaining operations and has good documentation. Decimal.js has a more extensive API due to its broader range of mathematical operations. It has a steeper learning curve and may require more effort to use effectively.
Both Currency.js and Decimal.js have active communities and receive regular updates. Currency.js has a larger community and ecosystem, which means more community-contributed resources, plugins, and integrations. Decimal.js, although smaller, is still well-maintained and has a dedicated community.
