There basically already is in the M1: https://www.anandtech.com/show/16226/apple-silicon-m1-a14-deep-dive/2 https://www.anandtech.com/show/16226/apple-silicon-m1-a14-de... tl;dr it has really sick floating point double performance which directly translates to JS performance

Most JavaScript JITs do math on integers.

  Only if using the BigInt type: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Number https://developer.mozilla.org/en-US/docs/Web/JavaScript/Refe... all other numbers are floats

    No, this is independent of BigInt. JITs speculate that numbers are integers for performance.
