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 is based on a subset of the JavaScript Programming Language Standard ECMA-262 3rd Edition - December 1999. JSON is a text format that is completely language-independent but uses conventions that are familiar to programmers of the C-family of languages, including C, C++, C#, Java, JavaScript, Perl, Python, and many others.

Why Use JSON?

  • Data Interchange: JSON is used for transmitting data between a server and a web application as an alternative to XML.
  • Human-Readable: JSON's structure is simple and clear, making it easy to read and understand.
  • Lightweight: Compared to XML, JSON is more compact and less verbose, resulting in faster data transmission and processing.
  • Language-Independent: JSON is a text-based format, so it can be used with any programming language.
  • Easy Parsing: JSON data can be easily parsed and used by most programming languages and platforms.
  • Object Representation: JSON's object-based structure makes it a natural way to represent data in applications.

JSON Example:

{
  "firstName": "John",
  "lastName": "Doe",
  "age": 30,
  "address": {
    "street": "123 Main St",
    "city": "Anytown",
    "country": "USA"
  },
  "phoneNumbers": [
    { "type": "home", "number": "555-1234" },
    { "type": "work", "number": "555-5678" }
  ]
}
