Script Preparation code:

var i = 0;
var initialString = "This is the initial Test String";
var encoder = new TextEncoder();
var view = encoder.encode(initialString);
var initialObject = {someString: initialString};
var initialStringify = JSON.stringify(initialObject);

var decoder = new TextDecoder();

Tests:

Encode
var newString = "This is the updated Test String"; var view = encoder.encode(newString); if (i == 5000) console.log(view); i++;
EncodeInto
var newString = "This is the updated Test String"; var view = encoder.encodeInto(newString); if (i == 5000) console.log(view); i++;
JSON.Stringify
var newString = "This is the updated Test String"; var object = {someString: newString}; var stringify = JSON.stringify(object); if (i == 5000) console.log(stringify); i++;
Decode
var decoded = decoder.decode(view); if (i == 5000) console.log(decoded); i++;
JSON.Parse
var parse = JSON.parse(initialStringify) if (i == 5000) console.log(parse);
