BigInt is a built-in object whose constructor returns a bigint primitive — also called a BigInt value, or sometimes just a BigInt — to represent whole numbers larger than 2^53 - 1 (Number.MAX_SAFE_INTEGER), which is the largest number JavaScript can represent with a number primitive (or Number value). BigInt values can be used for arbitrarily large integers.
