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
