has-bigints reliably detects whether the current JavaScript environment supports native BigInts. It offers a boolean result, crucial for libraries and applications needing to conditionally use BigInt functionality. This small, dependency-free package ensures accurate detection across various browsers and Node.js versions. Using has-bigints prevents errors when BigInt operations are attempted in environments lacking support, improving code robustness and user experience. It simplifies feature detection, especially important in code targeting diverse JavaScript runtimes.
