Did you know there is a limit to how big of a number you can represent in JavaScript when writing ?

const maxHighValue = 9007199254740991;
const maxLowValue = -9007199254740991;

// If you go one over/below these numbers then you start to get into dangerous territory.

const oneOverMax = 9007199254740992;
const oneBelowMin = -9007199254740992;

// The solution for handling numbers of this size is to convert these numbers to BigInts instead of a number: https://developer.mozilla.org/docs/Web/JavaScript/Reference/Global_Objects/BigInt TypeScript will now offer a fixit for number literals which are above 2^52 (positive / negative) which adds the suffix "n" which informs JavaScript that the type should be BigInt.
