How to extract values from a string in ESP8266?

Is it possible to parse JSON in ESP8266?
This post shows how easily is to parse JSON in the ESP8266. Naturally, this allows to change data in a well known structured format that can be easily interpreted by other applications, without the need for implementing a specific protocol.
