what is json

Quick Scoop

JSON stands for JavaScript Object Notation. It is a lightweight, text- based format for storing and exchanging data, and it is easy for both people and computers to read.

What JSON Looks Like

JSON uses:

• Objects with curly braces { }.
• Arrays with square brackets [ ].
• Key-value pairs like "name": "Ava".
• Common values such as strings, numbers, booleans, null, arrays, and nested objects.

Example:

json

{
  "name": "Ava",
  "age": 25,
  "isStudent": false,
  "skills": ["Python", "SQL"]
}

Why People Use It

JSON is widely used in web apps because it makes it simple for a browser, server, or API to exchange structured data. It is also language-independent, so many programming languages can read and write it easily.

Key Rule

Standard JSON does not allow comments, and keys must be in double quotes.
