What is JSON?
JSON (JavaScript Object Notation) is a lightweight data exchange format. It represents data objects in a text format that is easy for humans to read and write, and is ideal for sending data from back-end servers to web or mobile applications.
Why use JSON for front-end and back-end interactions?
Front-end and back-end interactions require a data format specification to ensure that both sides can correctly parse and process the received data. In many web applications and mobile applications, the front end uses JavaScript and Ajax techniques to send requests to the back end, so JSON is one of the most common data formats.
The benefits of using JSON include:
- Readable : JSON data is easy for humans to read and write.
- Small size : Compared to other data formats such as XML, JSON format data is more compact, which means that data can be transferred and processed faster.
- Extensive support : JSON supports numerous programming languages such as C, C++, C#, Java, Perl, Python, and more.
- Ease of parsing : Since JSON objects are usually manipulated via JavaScript, it is convenient to use JSON parsing on the front end.
Is there any other way?
Of course, there are many other data formats to choose from besides JSON, such as XML, YAML, and CSV. However, considering that JSON is relatively lightweight, easy to read and parse, and has been widely supported, it is usually the selected and recommended data format for front-end and back-end interactions.
