JSON vs YAML

JSON Format

JSON (JavaScript Object Notation) is a widely-used data format:

{
  "name": "John",
  "age": 30,
  "skills": ["JavaScript", "Python"]
}

YAML Format

YAML (YAML Ain't Markup Language) is human-friendly and uses indentation. Learn more about YAML →

name: John
age: 30
skills:
  - JavaScript
  - Python

Use Cases

  • Configuration files (Docker, Kubernetes use YAML)
  • API request/response formatting (JSON)
  • Data interchange between systems
  • Converting between human-readable and machine-readable formats
  • CI/CD pipeline configurations

Key Differences

  • Syntax: JSON uses brackets/braces, YAML uses indentation
  • Quotes: JSON requires quotes for strings, YAML doesn't
  • Readability: YAML is more human-readable
  • Comments: YAML supports comments (#), JSON doesn't
