What is JSON, and what is its coding structure?

These days, most people meet their needs through various sites and can do a lot of tasks through it, because they can get what they want easily with just one click, so it is being added to various sites that provide services to users day by day, due to the increase in the number of different sites, it is the users who must choose a site from them to receive the service they need, so the owners of different sites must be very careful while  designing their site, so that it can persuade the user to choose it.

One of the programming languages that can help site designers is JavaScript, and one of the branches of which, is  JSON, which we are going to discuss in more detail and explain the structure of the code in it, but before that, it is necessary to give a brief explanation of JavaScript.

What is JavaScript?

There are many programming languages, one of which is JavaScript, which allows programmers to make their websites more beautiful to provide a positive experience for users who visit them. This language has a lot of fans among programmers who prefer to use it to add items such as animation, interactive forms, etc., to the content with the help it.

What is JSON?

It stands for  JavaScript Object Notation  which is often used to store and send data from a web server to a web page, and it is easy to understand because its code is self-describing. In other words, it can be so helpful when the data, which should be in the form of text, is transmitted between a browser and a server. It is also possible to convert any JavaScript object to it; once this data is transmitted to the server in the form of text, it can be converted to JavaScript objects on the server. As a result, data can be transferred easily, as we have mentioned before.

How to write it:

- To write these codes, you must create data pairs (name/value).

- You must use a comma to separate the data you have entered.

Sending data:

To transfer the data stored in JavaScript to the server, you need to convert it to JSON; if you want to learn more, pay attention to the following example.

Receiving Data:

Also, if you receive data in JSON format, you can convert it to JavaScript, as the example which is mentioned below.

How to store information:

As mentioned earlier, you can use JSON to store various information and save it by converting it to text; for a better understanding, you should pay attention to the following example.

Note the following:

One of the most important points is that because the data is stored in text, it is possible to send it from a server easily; after receiving the data, it is possible to use it like any JS object.

What is XML?

It stands for  Extensible Markup Language, which is a programming language, and it is used to categorize as well as transfer data; here, you can see an example of its codes.

Comparison of JSON and XML:

As you know, both of them are used to transfer and store information; in the following, we will compare these two.

- JSON is more popular than XML because most programmers know how to work with JavaScript, and because it is a subset of JS, those who are fluent in this language do not need to spend a lot of time learning a different thing when it comes to programming with this subset.

- Another reason different programmers are interested in using it is that the code in it is clean. It is also easier to understand compared to XML; in fact, at first, an XML file can be easily understood, but due to a large number of tags, programmers still have to spend more time to understand them while they can reach their goals easily by choosing JSON to do their task.

- As you know, these two are used to store data and transfer it. Still, the point is that converting JSON to a JavaScript object requires only one line of codes, and you do not need to have information about the object that will be parsed, but it is not the case with XML because it requires thousands of lines of codes.

Note the following while using it:

- When developers use it, they have to use strings to display the date.

- In this language, it is not possible to annotate the code, which in fact, is one of the negative points of this language that if you want to annotate your code, you have to generate new files, which can take more time as well as more energy.

- It is possible for you to display the data in a way that you want while using this item for programming, which seems to be one of its positive points that can cause an error because this flexibility makes you create incorrect data in the case that you are not careful enough and do incorrect coding.

- As you know, it has a shorter data format than XML; however, it cannot be said that it is the shortest way to display data.

Last word:

As you know, programming has many fans and the number of the fans in this field is increasing day by day, and all of them are trying to be able to search and study the best available facilities to do their work in the best way possible and achieve their goal, one of the things they can do in order to store and transfer their data from the web server to the web is JSON, which we have discussed, in this article, as a result, there is a possibility for you as a person who is interested in programming to learn and use it because as we mentioned, it is very easy to work with, and you can create clean coding that is easy to understand which is of a great importance, as a result, the essential points about it, was mentioned in this regard which we hope can be useful for you in order to help you achieve your desired results due to the fact that it can be so helpful for you if you are interested in this field, and it is also a perfect option for you if you knew how to work with JS, because this is one of its subsets, as a result, they do not have to learn anything new, which can be considered as a positive point due to saving time as well as energy, therefore it can be a good option to choose.
