JSON is an open standard file format and data interchange format that uses human-readable text to store and transmit data objects consisting of attribute–value pairs and arrays (or other serializable values). It is a common data format with a diverse range of functionality in data interchange including communication of web applications with servers. JSON files are encoded for many important reasons, one of which to is done to protect the source code of web application, which is public (HTML, JavaScript, CSS) in order to be compiled by the browsers. The main point here is to protect our code from reverse engineering, tempering and stealing.
