var a = [...Array(10000)].map(_ => Math.random());
var ta = (new Float64Array(10000)).map(_ => Math.random());
Tests:

  • array reverse

     
    a.reverse();

  • typedArray reverse

     
    ta.reverse();

  • array i/o

     
    for (let i = 0; i < 10000; ++i)
      a[i] = a[i] + 1;

  • typedArray i/o

     
    for (let i = 0; i < 10000; ++i)
      ta[i] = ta[i] + 1;
