What is JSON and how do I parse it in JavaScript?
Asked on Aug 24, 2024
Answer
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. In JavaScript, you can parse JSON using the `JSON.parse()` method.
<!-- BEGIN COPY / PASTE -->
const jsonString = '{"name": "John", "age": 30, "city": "New York"}';
const jsonObject = JSON.parse(jsonString);
console.log(jsonObject.name); // Output: John
<!-- END COPY / PASTE -->Additional Comment:
✅ Answered with JavaScript best practices.- JSON is often used to transmit data between a server and a web application.
- The `JSON.parse()` method converts a JSON string into a JavaScript object.
- Ensure the JSON string is properly formatted; otherwise, `JSON.parse()` will throw an error.
