Big.js is a JavaScript library that provides arbitrary-precision decimal arithmetic. It allows you to perform precise calculations with decimal numbers, avoiding the rounding errors that can occur with native JavaScript number handling. Big.js supports a wide range of mathematical operations, including addition, subtraction, multiplication, division, and more.
Decimal.js is a JavaScript library for precise decimal arithmetic. It provides a reliable and accurate way to perform calculations with decimal numbers, avoiding the common rounding errors and precision issues that can occur with floating-point arithmetic in JavaScript.

Popularity
Both Big.js and Decimal.js are popular npm packages for performing arbitrary precision arithmetic in JavaScript. Decimal.js is slightly more popular and widely used than Big.js in the JavaScript community.
Precision
Both libraries provide support for arbitrary precision arithmetic. Big.js uses a base-10 arithmetic approach, while Decimal.js uses a base-2 arithmetic approach. Decimal.js offers higher precision and more advanced mathematical operations than Big.js.
Performance
In terms of performance, Big.js is generally faster than Decimal.js. Big.js is optimized for fast integer and floating-point operations, making it more suitable for performance-critical applications.
Ease of Use
Both libraries have a similar API and are easy to use. However, Decimal.js provides additional functionality like formatting, rounding, and modular arithmetic, making it more convenient for certain use cases.
Dependencies
Big.js has no external dependencies, making it lightweight and easy to integrate into projects. Decimal.js, on the other hand, has a dependency on the BigNumber.js library, which may increase bundle size and introduce additional complexity.
Compatibility
Both packages are compatible with JavaScript and can be used in various environments, including Node.js and browsers. They also both have TypeScript support, providing type declarations for improved development experience and error checking.
