Script Preparation code:

var bytes = new Uint8Array([1,2,3,4])
var offset = 0

Tests:

DataView
for (var i = 0; i < 10000; i++){ const x = new DataView(bytes.buffer, bytes.byteOffset).getUint32(offset) }
Direct
for (var i = 0; i < 10000; i++){ const x = ( bytes[offset] << 24 | bytes[offset + 1] << 16 | bytes[offset + 2] << 8 | bytes[offset + 3] ) }
