JavaScript's standard number type has a limit of 1.8 x 10^308, which can be exceeded in cryptographic algorithms and scientific calculations. `BigInt` allows working with arbitrary-precision integers, limited only by available memory, enabling precise calculations and accurate results with very large numbers.
JavaScript's built-in Number type has limitations when working with extremely large integers. That's where BigInt comes in – a new data type designed for handling arbitrary-precision integers, making it suitable for applications requiring large values.
