Hi Amod, this was extremely helpful. One quick doubt.
As mentioned, on passing root node($), System.out.println((Object)jsonPath.get("$")), we are getting the entire JSON object.

But, to fetch the value of field "firstname", if we are writing Json path as "$.firstname" instead of "firstname", it is giving null value.
Can you please explain the reason behind this?
// prints null
//prints null
