JavaScript is a programming language that has many fans among different programmers. One of the branches of this language is Jason, which can help you a lot in the field of programming when data is exchanged between a browser and a server, it can be textual, but it cannot be an object or anything else, JavaScript Object Notation can help you in this direction because it is possible to convert any JavaScript object to it and finally transfer it from the browser to the server.
In the following, we will deal with the issues that exist in this regard which are of great importance, so that you can increase your awareness in this field and do your tasks with more mastery.
Types of data in JSON:
There are different types of data in Json, which we are going to mention the following types of data in this case.
- String:
The requirement for this data is that the content, which is a string, be written in double-quotes, now take a look at the example below to find out more.
{ "name":"J" }
- Number:
These numbers may be integers, or they may be floating points. Now consider the following example, which is an integer.
{ "age":20 }
- Object:
The values in Jason may be the object.
Consider the following example.
{
"employee": { "name":"Jack", "age":20, "city":"New York" }
}
- Array:
The available values may also be in the form of an array. To understand this part better, pay attention to the following example.
{
"employees":[ "Jack", "Rose", "Michel" ]
}
- Boolean:
In this case, the available values may be true or false.
{ "sale":false }
- Null:
Another factor that may have different values is to be null. An example is mentioned below in this regard.
{ "middlename":null } The point about values in JSON is that existing values cannot be function, date, and undefined. In the section above, we have mentioned different values with examples. Now it's time to deal with JSON Objects.
JSON Objects:
One of the most important things in Jason is Objects. In this programming language, they are surrounded by {}, these items are written as a pair of existing values, and they are as string. Other values may be as string, number, zero, boolean, and so on, keys and values are separated by a colon, a comma separates each key/value pair.
Note the following example where we can access object values using the dot symbol and change the object's value.
The result of the above example will be as follows.

Another way to access object values is using ([]). An example is given in the following, which can help you understand this part better.
The result of the example will be as follows:
Access a JSON object using bracket notation:
Rose
Loop through JSON:
This can be used to review the object's properties, which you can find out more about by paying attention to the following example.
The result of this example will be as follows.

name
age
car
The important thing about using a loop is using the bracket to access property values.
The result of the above example will be as follows.
Use bracket notation to access the property values.
Rose
20
null
You can also gain access to Nested JSON Objects by using a semicolon or a bracket. Now pay attention to the example which is given in this regard.
The result of the above example will be as follows.

Modify Values:
One of the features of this language, which can be very helpful for you as a programmer, is that you can use a dot to change any of the values in a JSON object.
The result of the above example will be as follows.

Interestingly, you can use the bracket to change its value of it. An example is given below in order to help you understand this better.
The result of the above example will be as follows.

Delete:
To delete the properties of an object, you can use the delete keyword, an example of which is given below, which helps you understand it better.
The result of the above example will be as follows.

Last word:
In general, there are several features in JSON that can be used in order to help programmers. In this article, we have mentioned two of them with their examples so that you can find out more about the subject, but JSON is actually a brief exchange of data between a browser and a server and converts the existing data in the form of objects into text and finally transfers them, then you can convert any JSON received from the server into JavaScript objects.
Through this way, you can work with data as JavaScript objects without complicated analysis and translation and enjoy using it as much as possible, and if you pay attention to the point which has been mentioned in this article, you can use this language with more awareness of the various possibilities that exist, for example, the features that exist in relation to various data as well as objects in order to get the best possible result from using Jason.
