BigInt Shipping in Firefox
Kind of bummed this is a new primitive type. Every instance of `typeof a === 'number'` just became `typeof a === `number` || typeof a === 'bigint'`...<p>EDIT: The more I think about it (and the more comments I get), the more I think this might actually be a good thing. I think bigint will probably not be used in places where integer numbers are currently used, and it might be unreasonable to expect code to work with numbers or bigints. In that case, it's actually probably good that you can easily tell the difference using typeof, without requiring some hacky fix like `Array.isArray`.<p>It does mean that "don't mix numbers and bigints" is going to become very popular JS advice soon.
