What is JSON and its common operations?

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.

      const obj = JSON.parse(jsonString);
      

• Example:

        const jsonString = '{"name":"John","age":30}';
        const obj = JSON.parse(jsonString);  // { name: "John", age: 30 }
        

1. Stringification: Converting a JavaScript object into a JSON-formatted string, commonly used for data transmission or storage.

      const jsonString = JSON.stringify(object);
      

• Example:

        const obj = { name: "Jane", age: 25 };
        const jsonString = JSON.stringify(obj);  // '{"name":"Jane","age":25}'
