Javascript object Vs JSON

Question

I want to understand the basic differences clearly between Javascript object and JSON string.

Let\'s say I create the following JS variable:

var test         


        

Answer 1

Q1 - in JS you only need to use quotes if the key is a reserved word or if it would otherwise be an illegal token. In JSON you MUST always use double quotes on key names.

Q2 - the jsonString is a serialised version of the input object ...

Q3 - which may be deserialised to an identical looking object using JSON.parse()
