What is JSON structure?
A JSON object contains zero, one, or more key-value pairs, also called properties. The object is surrounded by curly braces {} . Every key-value pair is separated by a comma. The order of the key-value pair is irrelevant.
What defines JSON?
JavaScript Object Notation (JSON) is a standard text-based format for representing structured data based on JavaScript object syntax. It is commonly used for transmitting data in web applications (e.g., sending some data from the server to the client, so it can be displayed on a web page, or vice versa).

Why is JSON important?
What are the features of JSON?
Features of JSON
- JSON is Scalable. Because of language-independent, it works with most of the modern programming language.
- JSON is lightweight.

What are the advantages of JSON?
Benefits of JSON
- JSON is self-describing. The syntax and hierarchical structure of the JSON strings can in some cases be interpreted by applications that do not already know what data to expect.
- JSON is simple text.
- JSON is compact.
- JSON is easy to learn, easy to read, and easy to understand.
