📘 Learn: JSON, Base64 & Why Formatting Matters

Everything you need to understand JSON, Base64, examples, and real-world use cases.

🎯 How JSON Works

JSON (JavaScript Object Notation) is a lightweight format for data exchange. It uses objects, arrays, and key–value pairs to structure data.

Example JSON Structure

{
  "name": "John",
  "age": 25,
  "skills": ["C#", "ASP.NET", "AI"]
}

🎯 What Base64 Is

Base64 is an encoding that converts binary files (PDFs, images, documents) into text.

  "age": 25,
  "skills": [
    "C#",
    "ASP.NET",
    "AI"
  ]
}
