Benchmark: sin vs fast sin - MeasureThat.net

Script Preparation code:

const PI = Math.PI;
const TAU = PI * 2;
const B = 4 / PI;
const C = -4 / TAU;
var sin = x =>  {
    return (B * x + C * x * ((x < 0) ? -x : x));
};

Tests:

Math.sin
let k = []; for (let i = 0; i < 100; ++i) k.push(Math.sin(i));
fast sin
let k = []; for (let i = 0; i < 100; ++i) k.push(sin(i));
