Number.MIN_SAFE_INTEGER

The Number.MIN_SAFE_INTEGER constant represents the minimum safe integer in JavaScript (-(2^53 - 1)).

To represent integers smaller than this, consider using BigInt.

The MIN_SAFE_INTEGER constant has a value of -9007199254740991 (-9,007,199,254,740,991 or about -9 quadrillion). The reasoning behind that number is that JavaScript uses double-precision floating-point format numbers as specified in IEEE 754 and can only safely represent numbers between -(2^53 - 1) and 2^53 - 1. See Number.isSafeInteger() for more information.

Because MIN_SAFE_INTEGER is a static property of Number, you always use it as Number.MIN_SAFE_INTEGER, rather than as a property of a Number object you created.
