var a = [...Array(10000)].map(_ => Math.random());
var av2 = [...Array(10000)].map(_ => Math.random());
var ta32 = (new Float32Array(10000)).map(_ => Math.random());

Tests:

  • array sort [Async/Deferred]

     
    a.sort();

  • Float32Array sort [Async/Deferred]

     
    ta32.sort();

  • Float64Array sort [Async/Deferred]

     
    ta64.sort();

  • array dot

     
    let sum = 0.0;
    for (let i = 0; i < 10000; ++i) {
      sum += a[i] * av2[i];
    }

  • Float32Array dot

     
    let sum = 0.0;
    for (let i = 0; i < 10000; ++i) {
      sum += ta32[i] * ta32v2[i];
    }

  • Float64Array dot

     
    let sum = 0.0;
    for (let i = 0; i < 10000; ++i) {
      sum += ta64[i] * ta64v2[i];
    }
