Advantages of JSON
JSON is easy to learn and simple to read and understand. Plus, its format is text-only, so it can be easily sent across servers. In fact, web applications prefer JSON over XML as it is faster and easier to parse. Some other benefits of JSON are as follows:
1. Fast and efficient
Additionally, JSON is lightweight and compact. Therefore, the same data in JSON will be almost two-thirds of the XML. This is to say, using only JSON, you can perform the same functions as XML with fewer characters. The obvious advantage of this is that it results in faster execution. Overall, this makes JSON quick and efficient in performing functions. The other benefit of uncomplicated syntax is that it simplifies data access.
JSON is an easy-to-parse data format. You don’t need any additional code for parsing, either. The perk of JSON server-side parsing is that it increases responsiveness. That way, the clients can get faster responses to their queries. For this reason, JSON is widely adopted as a standard data exchange format. Other than this, if you are working with an object-oriented system, JSON can be your go-to as it can be easily mapped. The reason for easy mapping is that it is data-oriented, whereas its counterpart XML is document-oriented.
3. Key/Value pair approach
The JSON object is rendered in curly brackets, with the key/value pairs inside the space. The key, as well as value, are wrapped in double quotation marks (” “). They are separated by a colon (:) and commas (,), i.e., those characters divide these pairs. The key/value approach utilized by JSON makes it a simple data format. It also streamlines write and read operations.
4. Data sharing
Out of several functions of JSON, the notable one is sharing of data. It is used to establish a connection between front-end and back-end languages for sharing data. Firstly, the front-end language is converted to JSON text, which is known as serialization. Then, the JSON text is converted to programming data, which is known as deserialization. The process of serialization and deserialization is quite fast in JSON, eventually promoting sharing of structured data.
5. Extensive browser support
As we have outlined above, JSON is an independent data format. Therefore, it is supported by most browsers. This is to say that almost all programming languages have functions or libraries that support JSON. A few browsers that support JSON are Chrome 3 and above, Internet Explorer 8 and newer, Safari 4 and above, Firefox 3.5 and later, and Opera 10.5 and higher.
Disadvantages of JSON
The compact form of JSON has its downsides. The developers have to follow the restrictive specifications of the JSON. Otherwise, it can lead to complications in the implementation of the JSON parser. This has an impact on the writability and readability of the code to a certain extent. The following are other drawbacks of JSON:
1. No date data type
JSON includes data types such as string, number, object, array, boolean, and null. But it skips the date data type. The lack of the date data type in JSON forces developers to look for an alternative. One way to represent the date is using the string data type. However, this can create discrepancies in the formatting. Also, changing the JSON data into another format is tedious. Whereas in XML, you can easily achieve this using the XSLT template. The built-in support for format change in XML is quite beneficial, but there is no similar support in JSON.
Verbosity on this list might come as a surprise, considering we have emphasized how easy and compact JSON code is. Surely, JSON uses fewer characters than its counterparts. But the same feature becomes a drawback when you are working on special-purpose projects. The reason is: JSON code isn’t concise, which defeats the purpose of using it. In these cases, you might want to explore other data formats that will give you the efficiency and results you are looking for.
3. Lack of comments
The comments are essential in understanding the code. You can use comments in JSON but with limitations. This is to say, you’ll have a hard time clarifying the data in the data itself. Also, comments are not allowed by some JSON libraries as inputs. In such cases, you will need to use the preprocessor to remove those comments. However, this leads to additional work of editing in order to parse the file.
4. Less secure
