building/modifying JSON with javascript

modifying_json.js

// https://developer.mozilla.org/en-US/docs/JSON
var foo = {};
foo.bar = "new property";
foo.baz = 3;
var JSONfoo = JSON.stringify(foo);

// JSONfoo now holds {"bar":"new property","baz":3}

// To make JSONfoo back into a JavaScript object just do:
var backToJS = JSON.parse(JSONfoo);
