Extract missing flattened keys from a JSON after comparing it to another JSON (dictionary JSON).

Usage:
Copy your JSON (the one which has / may have missing keys), goto browser console, then type var x = then paste the copied JSON.
Copy your dictionary JSON (the one which has all the keys), goto browser console, then type var y = then paste the copied JSON.
Then copy the code from compareAndGetMissingJSONKeys.js and save it as a browser bookmark.
Remember, ‘y' is your JSON dictionary, 'x’ is your missing-keys-JSON.
Click the bookmark, you’ll get an array of flattened keys that is missing, in your browser console.

Example:

Input x:

Input y:
