Bigint support #22

Closed tomtheisen closed 5 years ago

tomtheisen commented 5 years ago

Bigint is now supported by chrome and node. https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/BigInt

This library is not compatible with these numbers. isNumber(7n) reports false.

According to the documentation that you linked, it is not recommended to coerce variables between Number and BigInt. It also states that native Math methods do not work with BigInt.

Because of these restrictions, I don't think is-number should return true for BigInt.
