Benchmark: JSON.parse vs dataview vs typedarray

Script Preparation code:

var intObj = {alpha:12345678,beta:12345678,charlie:12345678,delta:12345678,foxtrot:12345678}
var typedArray = new Int32Array(12345678,12345678,12345678,12345678,12345678)
var buffer = new ArrayBuffer(20)
var dv = new DataView(buffer)
dv.setInt32(0,12345678)
dv.setInt32(4,12345678)
dv.setInt32(8,12345678)
dv.setInt32(12,12345678)
dv.setInt32(16,12345678)

Tests:

JSON
let stringy = JSON.stringify(intObj); let parsed = JSON.parse(stringy); let a; a = parsed;
TypedArray
let newBuffer = typedArray.buffer let parsedBuffer = new Int32Array(newBuffer) let b; b = parsedBuffer;
dataview
let dvBuffer = dv.buffer let newView = new DataView(dvBuffer) let c; c = newView;
