Advantages of JSON

  • Easy for humans to read and write
  • Easy for machines to parse and generate
  • Supports multiple programming languages
  • Simple data format with high transmission efficiency
  • Widely used in web applications

JSON Use Cases

  • Web API data exchange
  • Configuration file storage
  • Data persistence
  • Cross-platform data exchange
  • Mobile application development

What is JSON?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It's based on a subset of JavaScript syntax.

JSON Syntax Rules

  • Data is in name/value pairs
  • Data is separated by commas
  • Curly braces hold objects
  • Square brackets hold arrays
  • Strings must be in double quotes

Common JSON Data Types

  • String: "Hello World"
  • Number: 42
  • Boolean: true/false
  • Null: null
  • Array: [1, 2, 3]
  • Object: {"name": "John"}

Best Practices

  • Use meaningful key names
  • Keep the structure consistent
  • Validate your JSON before using it
  • Use proper indentation for readability
  • Handle special characters properly
