What are the benefits of using JSON over XML?

This article will introduce to you what are the benefits of using JSON compared to XML? Let everyone know whether to use XML or JSON during development. It has certain reference value. Friends in need can refer to it. I hope it will be helpful to you.

XML: Extensible Markup Language, once the only option for open data exchange. However, the growth of open data sharing gives developers more options, each with its own set of benefits. While XML may be a widespread API integration method, that doesn't mean it's the best choice for your project.

JSON: JavaScript Object Notation, is another option that attracts a lot of attention. When you mention JSON to developers, the first thing that comes to mind is that it is lightweight compared to other open data exchange options. However, that's not the only reason why you should use it for your next RESTful API integration.

Let’s take a lookWhat are the advantages of JSON compared to XML?

More concise and easy to debug (readable)

JSON has a more compact style than XML and is generally more readable. JSON's lightweight approach can provide significant improvements in RESTful APIs using complex systems.

The JSON structure is simple and easy to read. No matter what programming language you use, it's easier to map to domain objects.

Faster and lower bandwidth utilization

The XML software parsing process may take a long time. One reason for this problem is that DOM manipulation libraries require more memory to handle large XML files.

The database size in JSON is smaller than XML, but the same data can be conveyed, so data transfer between client and server is faster, and round-robin helps reduce network traffic because fewer words Throttling the amount of traffic across the line enables servers to get faster completions and clients to respond faster. Simply put: JSON uses less data overall, thus lowering costs and increasing parsing speed.

JSON objects and code objects are matched, which is very useful when using dynamic languages ​​to quickly create domain objects.

Less memory footprint, faster generation and processing

JSON's data structure is smaller, resulting in lower memory utilization on both client and server esp. In client-side size, helps browsers accept larger-scale JSON documents and parse them quickly using large amounts of client-side CPU and memory, making the browser interface more responsive.

Browser support via Javascript

Another important benefit is that you can use JavaScript’s eval() function to parse JSON text. No special libraries are required and this works across all browsers, so no need to worry about cross-browser issues. As long as the browser has JavaScript enabled and supports this eval() function, you can parse JSON data.

Supports many languages

Major languages ​​such as javascript, python, C, and C are all supported

Summary:

When describing the same data, the amount of data generated by JSON is smaller than that generated by XML, which is more conducive to transmission on the network; at the same time, the JSON format is more intuitive and easier to understand than XML, so many people Prefer to use JSON.
