JavaScript gets a new numeric primitive that provides support for arbitrary-precision integers. `Number`s in JavaScript are represented as double-precision floats, giving them limited precision. `BigInt`s, on the other hand, can safely store and operate on large integers even beyond the safe integer limit for `Number`s.
