/**
* Parses a string of well-formed JSON text.
*
* If the input is not well-formed, then behavior is undefined, but it is
* deterministic and is guaranteed not to modify any object other than its
* return value.
*
* This does not use `eval` so is less likely to have obscure security bugs than
* json2.js.
* It is optimized for speed, so is much faster than json_parse.js.
*
* This library should be used whenever security is a concern (when JSON may
* come from an untrusted source), speed is a concern, and erroring on malformed
* JSON is *not* a concern.
*
* Pros Cons
* +-----------------------+-----------------------+
* json_sans_eval.js | Fast, secure | Not validating |
* +-----------------------+-----------------------+
* json_parse.js | Validating, secure | Slow |
* +-----------------------+-----------------------+
* json2.js | Fast, some validation | Potentially insecure |
* +-----------------------+-----------------------+
*
* json2.js is very fast, but potentially insecure since it calls `eval` to
* parse JSON data, so an attacker might be able to supply strange JS that
* looks like JSON, but that executes arbitrary javascript.
* If you do have to use json2.js with untrusted data, make sure you keep
* your version of json2.js up to date so that you get patches as they're
* released.
*
* @param {string} json per RFC 4627
* @param {function (this:Object, string, *):*} opt_reviver optional function
* that reworks JSON objects post-parse per Chapter 15.12 of EcmaScript3.1.
* If supplied, the function is called with a string key, and a value.
* The value is the property of 'this'. The reviver should return
* the value to use in its place. So if dates were serialized as
* {@code { "type": "Date", "time": 1234 }}, then a reviver might look like
* {@code
* function (key, value) {
* if (value && typeof value === 'object' && 'Date' === value.type) {
* return new Date(value.time);
* } else {
* return value;
* }
* }}.
* If the reviver returns {@code undefined} then the property named by key
* will be deleted from its container.
* {@code this} is bound to the object containing the specified property.
* @return {Object|Array}
