It doesn’t require any additional explanation and is simple to read and get a grasp on. The JSON format, which is based on Javascript, was developed by Douglas Crockford. The majority of today’s programming languages, despite the fact that JSON has been around for quite some time, are able to generate and parse the data format.
The common data format known as JSON is used for asynchronous communication between web browsers and servers. It has supplanted XML in many of the systems that are designed in the AJAX fashion. When compared to XML, this format is not only more space efficient but also much easier to decipher. The Content-Type HTTP header is always set to application/json by browsers and servers whenever a data exchange format is utilised.
