JSON to 8-bit-integer parsing (and visa versa)

JSON-intArray-converter.js

// JSON to Uint8Array parsing and visa versa
// (Intended Bluetooth communication on Cordova)

var JsonToArray = function(json)
{
	var str = JSON.stringify(json, null, 0);
	var ret = new Uint8Array(str.length);
	for (var i = 0; i < str.length; i++) {

It sounds like you want to reduce network traffic between the server and client. This is well known and optimized problem, and there's various solutions to go for depending on your priorities / most pressing motivation.

1. are you trying to learn about computer science?
2. are you trying to minimize costs?
   • do you consider your time spent on the optimization a cost?
3. do you want to minimize experienced latency?
4. are you trying to minimize network traffic?

I would not consider doing what you're thinking of in 99.9% of the cases of 2, 3 or 4.

Give me some more info about your situation, and maybe I can give better advice. You could also consider installing Cursor and asking AI - which has better answers and response times than most internet randos like myself
