Learn JSON - The API Response Format! Build Unique API-based Applications with JSON (javascript Object Notation)

JSON (javascript Object Notation) is a popular data interchange format. JSON has significantly improved server-to-browser communications, especially when it comes to AJAX. Most of todays APIs return the response in JSON format as it is much easier to load, read and process JSON compared to XML, making it very popular.

javascript Object Notation is text-based and human-readable. JSON is very easy to use with javascript as the syntax of JSON is a subset of javascript. Though it is a subset of javascript, JSON is language-independent. Most of the popular programming languages including PHP, Ruby, C#, Python etc. support JSON making it the widely used data interchange format.
