An easy and orderly way to save information is through JavaScript Object Notation (JSON). When information is transferred between a browser and a server, it must be in the form of text. Any JavaScript object can be converted to JSON and sent to the server in this manner.

Any JSON that you get from the server can also be converted into JavaScript objects. It makes working with the data as JavaScript objects easier because there is no need for laborious parsing and translations.

Now that you are aware of what JSON is, let's move on to why we must use it and what JSON's various benefits are.

JSON Syntax


// JSON syntax
{
    "name": "Shailesh",
    "age": 22,
    "gender": "male",

}

The data in JSON is organized into key/value pairs and separated by commas,.

JSON is a descendant of JavaScript. Consequently, the JSON syntax is similar to the JavaScript object literal syntax. However, other computer languages can also access and create the JSON format.

Data in JSON


Key/value pairs in JSON data resemble the object attributes in JavaScript. A colon separates the key and values, which are written in double quotes:. For instance,

// JSON data
"name": "John"

Object in JSON

A JSON object is enclosed with curly brackets. JSON objects are capable of holding several key/value pairs. For instance,

// Object in JSON
{ "name": "Shailesh", "age": 22 }

Array JSON


Square brackets [ ] are used to denote JSON arrays. For instance,

// Array JSON
[ "apple", "mango", "banana"]

// JSON array containing objects
[
    { "name": "Shailesh", "age": 22 },
    { "name": "Nadeem", "age": 20 }.
    { "name": "Suresh", "age": 23 }
]

What makes us use JSON?

The most popular format for data transmission (data interchange) between a server and client is JSON. JSON data are relatively simple to use and understand. JSON data are simple to retrieve and modify because they just include text.

JSON is not language specific. Other programming languages also support the creation and use of JSON.


When compared to other open data interchange solutions, JSON is compact and simple to use. You should use it for your API integration for a number of other reasons as well, though. It is chosen over alternative choices due to the following benefits:


Less Syntax - Compared to XML, it has a more condensed style. This makes it easier to read. Working with complex systems can be significantly improved by JSON's lightweight approach.


Faster - JSON is parsed by software more quickly than XML. This is due to the fact that large XML files require more RAM to be handled by the DOM manipulation modules. On the other hand, JSON requires less data, which lowers the cost and speeds up parsing.

Readable - JSON has a clear, simple structure that is simple to read. Whatever programming language you're using, you have an easier time mapping to domain objects.

Structured Data ? JSON uses a map data structure for its structured data, whereas XML uses a tree data structure. Your task may be constrained by the key or value pairs, but you get a predictable and simple data model in return.
