It has been the most crucial part of web development to exchange and store data on servers. Not even beginners but professional programmers are always digging up new methodologies to make this process smooth and swift. From the last two decades, XML has been on the horizon to accomplish the data exchange purpose. But a new alternate has been introduced to accelerate the process expeditiously, and it is called JSON.
JSON – Alternate to XML
JSON Syntax – Uplifting Server Correspondence
There are two layers of JSON, which is the foundational structure of this programming language. The structure stands itself on objects and Arrays.
Object: The assemblage of value pairs and name is known as an object in JSON.
Array: The methodical ordered-list of values by placing them in the proper format is known as arrays.
How to Declare Object in JSON
In the above example, the JSON data has been declared by using an object in the field. The object can vary, as it can be based upon sorting the data to fetch accordingly. It can either be person name, id, and other related information. While in the end, a Boolean is added to cross-check the authenticity of either the person is a student or not.
The object in JSON has specific formatting rules that need to be followed.
How to Declare Array in JSON
“Azerbaijan”, “Bangkok”, “England”, “Ireland”, “Thailand”, “Uzbekistan”
The above example of the classification of Array in the snippet depicts how JSON can be shaped as an array. Below are some of the rules for the declaration of arrays in JSON
In this part, we have discussed the declaration of arrays and objects in JSON; we will further elaborate on the use of values in JSON by writing another post.
