Basic Use of JSON
JSON is widely used to transfer data from one system to another. It can transfer data between two computers, a website, programs, etc.
It is widely used to transfer serialized data over a network connection.
It can be used with all major editing languages.
It is useful for transferring data from a web application to a server.
Many web services use a JSON-based format for transferring data.

JSON properties:
Let's summarize the properties:
· It is a light text-based data exchange format.
· Extended from JavaScript language.
· Its extension is .json.
· Being a text-based format is easy to read and write for both user/editor and machine.
· This is not independent of the programming language but also uses the most common conventions between the C-Family for languages such as C, C ++, C #, JavaScript, Java, Python, Perl, etc.
· So far, we have discussed JSON properties and uses. From here, we will discuss the structure of JSON or JavaScript Object Notion.
JSON has grown in need of a real-time server to a browser connection process that can work without using any additional plugins like java applets or flash. Therefore, after realizing the need for the real-time communication protocol, Douglas Crockford defined JSON in the early 2000s.
JSON was previously viewed as a subdivision of JavaScript and was used explicitly. But JSON integration code is available in almost every major language.
JSON syntax :
By now, you should have got some basic information about JSON. Let's take a look at the basic syntax used to build JSON.
JSON can be fundamentally divided by building on two structural elements. It is a set of name pairs and a list of numbers.
JSON is a universal data framework as most programming languages available today are self-supporting. It makes the editor work much easier to have a dynamic data type that can work in different languages.
Let us know more about these types of data:
A pair of word value pairs are found as an object, strut, record, dictionary, etc.
The order list is created as a program, list, etc.
We have seen almost all the basic ideas so far. Let's go ahead and look at the basic structure of JSON. In this example, we consider JSON to represent vehicle details.
Suppose we have a car item with the following basic features and features:
Make and model = Maruti Suzuki Swift
Make Year = 2017
Color = Red
Type = Hatchback
Therefore, if we want to transfer this data using the JSON file, editing this data will create JSON.
What JSON would look like:
Data Processing
We have seen the use of JSON, its basic design, and how data is presented in the JSON format. Now, let's take a look at how different elements are constructed in JSON.
What is JSON Object?
The JSON item is a set of keys and their values without any specific order.
The key and its values are combined using folded parentheses, both opening and closing “{}”. So, in the previous example when we created a JSON with a car attribute, we were actually creating a JSON car item. There are certain rules that need to be followed when building a JSON building, we will learn about those rules while discussing Key-value pairs.
So, in order to build JSON, the first thing we need is an attribute. Here, we create a JSON "Employee" item. The next thing we need to define object properties, let's assume our employees have a "First Name", "Last Name", "Employee ID" and "Name". These employee properties are represented as “Keys” in the JSON architecture.
Let's create a JSON item:
JSON item
Everything inside curly braces is known as the JSON Employee Object.
The basic JSON item is represented by a Key-Value pair. In the previous example, we used JSON to represent employee data.
We also represent the various employee structures; “First Name”, “Last Name”, “Employee ID” and “design”. Each of these "keys" has a value in JSON. For example, "First Name" is represented by the number "Sam". Similarly, we also represent other keys through different values.
General rules to follow when constructing JSON:
Ø JSON items must start and end with "{}" brackets.
Ø Key fields are included in the two quotes.
Ø Numbers are represented by placing the ":" column between them and the key.
Ø JSON key-value pairs are separated by a comma ",".
Ø Prices can be for any type of data such as String, Integer, Boolean, etc.
