BigInteger.js is an arbitrary-length integer library for JavaScript, enabling arithmetic on integers of unlimited size. It now acts as a thin wrapper over the native BigInt when the environment supports it.

Use cases

• perform arithmetic on integers larger than Number.MAX_SAFE_INTEGER
• parse and convert numbers in arbitrary bases
• polyfill BigInt support in older JavaScript environments
• compute factorials or modular arithmetic with huge numbers
• handle cryptographic-style large integer math in the browser

When to choose

• you need arbitrary-precision integers in JavaScript and must support environments without native BigInt
• you need flexible base conversion with custom alphabets
• you want a lightweight, dependency-free big integer library

When to avoid

• you only target modern environments with native BigInt support
• you need arbitrary-precision decimals or floats rather than integers
• you need very high performance heavy computation, where native BigInt or WebAssembly libraries may be faster
