TypeTags .BigInt

Overview#

BigInt is a built-in object whose constructor returns a bigint primitive to represent whole numbers larger than 2^53 - 1 or Number.MAX_SAFE_INTEGER, which is the largest number JavaScript can represent with a number primitive (or Number value).

Usage#

import { TypeTags } from 'typetags'

console.log(TypeTags.BigInt)
// → [object BigInt]

Predicate#

.isBigInt(value)#

• Checks if value is or has a default BigInt type tag.

const { TypeTags } = require('typetags')

let bigint = BigInt(45n)
TypeTags.isBigInt(bigint)
// → true

TypeTags.isBigInt(bigint.toString())
// → false

let tag = TypeTags.get(bigint)
TypeTags.isBigInt(tag)
// → true
