I'm learning javascript and just noticed that the syntax we use to define objects is the same as the json format. So I'm wondering if they are simply equivalent. Being more precise, does it mean that any javascript object (including its variables and functions) can be translated into json format and the same way around?

JSON is (like it's name "JavaScript Object Notation" indicates) a subset* of the JavaScript syntax, i.e. (nearly) every* JSON is valid JavaScript but not the other way round.
Functions, for example, have no equivalent representation in JSON and therefore, cannot be translated into JSON. Since the main purpose for JSON is serialization, it doesn't provide representation of statements either.
* There is one exception: more or less all Unicode characters can be written literally in JSON but they must be written using escape sequences in JavaScript. See this blog post for more information. So not every valid JSON is valid JavaScript.

Think of JSON as a string representation of your javascript object. - String being the key word here.
Primarily used for easy transport over HTTP .It is a method created by Douglas Crockford to enable a friendly Javascript data transfer format similar to XML , RSS, et all.
JSON is generally parsed by server and client back into a Javascript object for use.
