Benchmark: DataView vs TypedArray Float32 actually fixed

Script Preparation code:

var buffer1 = new ArrayBuffer(1024 * Float32Array.BYTES_PER_ELEMENT);
var array = new Float32Array(buffer1);
var buffer2 = new ArrayBuffer(1024 * Float32Array.BYTES_PER_ELEMENT);
var view = new DataView(buffer2);

Tests:

array[i] = i;
for (let i = 0; i < 1024; i += 1) { if (i === 0) { array[i] = 1; } else { array[i] = array[i-1] + i;; } }
view.setFloat32(i, i)
for (let i = 0; i < 4096; i += 4) { if (i === 0) { view.setFloat32(i, 1); } else { view.setFloat32(i, view.getFloat32(i - 1) + i); } }
array[i] = i; 2
for (let i = 0; i < 1024; i += 1) { if (i === 0) { array[i] = 1; } else { array[i] = array[i-1] + i; } }
view.setFloat32(i, i) 2
for (let i = 0; i < 4096; i += 4) { if (i === 0) { view.setFloat32(i, 1); } else { view.setFloat32(i, view.getFloat32(i - 1) + i); } }
