1. Data Format:
- JSON is used to represent structured data in a text-based format. It consists of key-value pairs enclosed in curly braces
{},
- where keys are strings and values can be strings, numbers, arrays, objects, booleans, or null.
2. Syntax:
- JSON syntax is simple and easy to understand. Each key-value pair is separated by a colon
: and pairs are separated by commas. String values are enclosed in double quotes ", and special characters can be escaped using backslashes \.
3. Data Types:
JSON supports several data types, including:
- Strings: Enclosed in double quotes
".
- Numbers: Integers or floating-point numbers.
- Arrays: Ordered collections of values enclosed in square brackets[].
- Objects: Unordered collections of key-value pairs enclosed in curly braces{}.
-
Booleans: true or false.
4. Human-Readable:
- JSON is designed to be easy for humans to read and write. Its simple and concise syntax makes it a popular choice for data serialization and configuration files.
5. Interoperability:
- JSON is language-independent and widely supported by programming languages and platforms. It is commonly used for exchanging data between web servers and clients in web applications.
6. Data Serialization:
- JSON is commonly used for serializing complex data structures into a string representation that can be transmitted over a network or stored in a file. JSON serialization is supported by many programming languages and frameworks.
7. Data Exchange:
- JSON is often used for exchanging data between different systems and components. It is used in web APIs, RESTful services, and microservices architectures for sending and receiving data between clients and servers.
8. Schema-less:
- JSON is schema-less, meaning that data does not need to adhere to a predefined schema or structure. This flexibility allows for dynamic and evolving data models.
9. Support for Nested Data:
- JSON supports nested data structures, allowing for the representation of hierarchical or nested data models. Objects can contain other objects or arrays, enabling the representation of complex relationships between data elements.
10. Lightweight and Efficient:
- JSON is lightweight in terms of both file size and parsing overhead. Its simplicity and efficiency make it well-suited for use in resource-constrained environments and high-performance applications.
