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;
