Decimal.js is a JavaScript library for arbitrary-precision decimal and non-decimal arithmetic. It provides accurate and reliable arithmetic operations on decimal numbers, avoiding common floating-point errors. Decimal.js is particularly useful for financial and scientific applications where precision is crucial.
The 'money' npm package is a versatile library for handling monetary values and currency conversions in JavaScript applications. It provides robust functionality for performing arithmetic operations, formatting currencies, and working with different currency codes. The library offers support for precision handling to avoid common pitfalls with floating-point arithmetic when dealing with financial calculations.

Popularity
Both decimal.js and money are popular npm packages in the JavaScript community. decimal.js has been around for longer and has a larger user base, while money is also well-known and widely used.
Decimal Handling
decimal.js is specifically designed for precise decimal arithmetic and provides a comprehensive set of methods for working with decimals. It offers features like decimal places rounding, mathematical operations, and formatting. On the other hand, money is a higher-level library built on top of decimal.js that focuses on handling monetary values with support for currencies, conversion, and formatting.
Flexibility
decimal.js is a standalone library that deals with decimal arithmetic in a general sense. It allows you to perform precise calculations on decimal numbers without any specific currency-related features. Money, on the other hand, is specialized for handling money values and provides additional functionalities related to currencies, conversions, and formatting.
Performance
decimal.js is optimized for precision and accuracy, but it may not be as performant as some other libraries that prioritize speed. Money, being built on top of decimal.js, inherits its performance characteristics. However, for most use cases involving money calculations, the performance difference is negligible.
Developer Experience
decimal.js provides a straightforward API with a wide range of methods for decimal arithmetic. It has good documentation and is generally easy to use. Money extends decimal.js with additional functionality related to monetary values, which can be handy for financial applications. However, it may introduce a slightly steeper learning curve due to extra features and concepts related to currencies.
Maintenance
Both libraries are actively maintained by their respective communities. decimal.js has a solid track record and has been reliably maintained over the years. Money, being a higher-level library that depends on decimal.js, also benefits from the ongoing maintenance efforts. Regular updates and bug fixes contribute to the overall stability and reliability of both packages.
