JSON stands for JavaScript Object Notation. It is a lightweight data format used for storing and exchanging data.
JSON is easy for humans to read and write, and easy for machines to parse.
Example JSON:
{
"name": "John",
"age": 25,
"email": "john@example.com"
}JavaScript can convert JSON to objects easily.
const data = JSON.parse(jsonString);And convert objects back to JSON:
const json = JSON.stringify(data);JSON is widely used in:
APIs
Web applications
Configuration files
Databases
Almost every modern web application uses JSON.
