BigInt: arbitrary-precision integers in JavaScript (via) The BigInt specification is now supported in Chrome—but it hasn’t yet made it to other browsers. The Chrome team have a really interesting solution: they’ve released a JSBI library which you can use to do BigInt calculations in any browser today, and an accompanying Babel plugin which can rewrite calls to that library into BigInt syntax once browser support catches up. I’ve never seen a library that includes a tool for refactoring itself into oblivion before.
