has-bigints

What is has-bigints?

The has-bigints npm package is a simple utility that allows developers to check if the JavaScript environment they are working in supports BigInts. BigInts are a type of data in JavaScript that can represent whole numbers larger than 2^53 - 1, which is the largest number JavaScript can reliably represent with the Number primitive. This package is particularly useful for writing code that needs to be compatible with various JavaScript environments, including older browsers or JavaScript engines that do not support BigInts.

What are has-bigints's main functionalities?

Checking for BigInt support

This feature allows developers to programmatically check if the current JavaScript environment supports BigInts. The function returns a boolean value, true if BigInts are supported and false otherwise. This is useful for conditional code execution based on BigInt support.

const hasBigInts = require('has-bigints');

if (hasBigInts()) {
  console.log('This environment supports BigInts.');
} else {
  console.log('BigInts are not supported in this environment.');
}

Other packages similar to has-bigints

big-integer

The big-integer package is a JavaScript library for arbitrary-precision integer arithmetic. Unlike has-bigints, which is a utility for checking BigInt support, big-integer provides its own implementation for handling large integers, making it useful in environments that do not support BigInt natively.

bignumber.js

bignumber.js is another library for arbitrary-precision arithmetic in JavaScript. Similar to big-integer, it does not rely on native BigInt support and can perform mathematical operations on large numbers. It offers more comprehensive features for arithmetic operations compared to has-bigints, which is solely focused on checking for BigInt support.

Determine if the JS environment has BigInt support.

Example

var hasBigInts = require('has-bigints');

hasBigInts() === true; // if the environment has native BigInt support. Not polyfillable, not forgeable.
