JSON (JavaScript Object Notation) is a lightweight, text-based data format that uses JavaScript object syntax for structuring data. It was popularized by Douglas Crockford and is widely used for transmitting data between a server and a client in web applications. JSON files typically have a .json extension and use the MIME type application/json.
#### Common Operations with JSON
1. Parsing: Transforming a JSON-formatted string into a native JavaScript object.
js
1const obj = JSON.parse(jsonString);- Example:
js
1const jsonString = '{"name":"John","age":30}';
2 const obj = JSON.parse(jsonString); // { name: "John", age: 30 }2. Stringification: Converting a JavaScript object into a JSON-formatted string, commonly used for data transmission or storage.
js
1const jsonString = JSON.stringify(object);- Example:
js
1const obj = { name: "Jane", age: 25 };
2 const jsonString = JSON.stringify(obj); // '{"name":"Jane","age":25}'Advertisement
