An Introduction to JSON: Characteristics and Syntax

JSON (JavaScript Object Notation)

JSON (JavaScript Object Notation) is a lightweight, human-readable, text-based data interchange format. It is designed for storing and transmitting data, commonly used for communication between a web server and a client, as well as for configuration files, logging, and data storage in specific databases. 

Key Characteristics:

Human-Readable: JSON's syntax is intuitive and straightforward, making it easy for humans to read and understand.

Text-Based: It uses plain text, which ensures compatibility across different systems and programming languages.

Language-Independent: While named after JavaScript, JSON is a language-independent data format. Parsers and generators exist for virtually all major programming languages.

Hierarchical Structure: It can easily represent complex, nested data structures.

Core Components of JSON Syntax:

Objects:

• Represented by curly braces {}.
• Contain unordered sets of key-value pairs.
• Keys must be strings enclosed in double quotes.
• Keys and values are separated by a colon:.
• Multiple key-value pairs are separated by commas.
• Example: {"name": "Alice", "age": 30}

Arrays:

• Represented by square brackets [].
• Contain ordered collections of values.
• Values are separated by commas,
• Example: ["apple", "banana", "orange"]

Values:

• Can be one of the following data types:
• String: Text enclosed in double quotes (e.g., "hello").
• Number: Integer or floating-point numbers (e.g., 123, 3.14).
• Boolean: true or false.
• Null: null.
• Object: A nested JSON object.
• Array: A nested JSON array.
