Why do we use JSON?

As a domain expert in data interchange formats, I can explain the reasons behind the widespread use of JSON (JavaScript Object Notation). JSON is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate. Here are some key reasons why JSON is used: 1. Lightweight: JSON is less verbose than XML, which means it uses fewer bytes to represent the same data, leading to faster data transmission. 2. Language Independent: Although JSON's syntax is derived from JavaScript, it is a language-independent format that can be used with many programming languages. 3. Native Support in Modern Languages: Many modern programming languages have built-in support for JSON, making it easier to work with. 4. Ease of Reading and Writing: JSON's syntax is similar to that of programming languages, which makes it more approachable for developers compared to XML. 5. Efficient Data Exchange: JSON is often used for APIs because it allows for efficient and straightforward data exchange between the client and server. 6. Widespread Adoption: Due to its simplicity and efficiency, JSON has become a de facto standard for web services, which has led to extensive tooling and community support.

JSON is JavaScript Object Notation. ... The JSON format is often used for serializing and transmitting structured data over a network connection. It is used primarily to transmit data between a server and web application, serving as an alternative to XML.
