toSafeInteger
Converts a value to a safe integer.
Use Math.max() and Math.min() to find the closest safe value.
Use Math.round() to convert to an integer.
const toSafeInteger = (num) =>
Math.round(
Math.max(Math.min(num, Number.MAX_SAFE_INTEGER), Number.MIN_SAFE_INTEGER)
);
toSafeInteger("3.2"); // 3
toSafeInteger(Infinity); // 9007199254740991
