How to process JSON data in JavaScript?

Processing JSON data in JavaScript involves parsing JSON strings into JavaScript objects and manipulating them as needed. The JSON.parse() method is used to convert a JSON string into a JavaScript object, while JSON.stringify() is used to convert a JavaScript object back into a JSON string.

Example of Parsing JSON:

let jsonString = '{"name": "John", "age": 30, "city": "New York"}';
let jsonObject = JSON.parse(jsonString);

console.log(jsonObject.name); // Output: John

Example of Stringifying JavaScript Objects to JSON:

let obj = {
  name: "Jane",
  age: 25,
  city: "Los Angeles"
};

let jsonString = JSON.stringify(obj);
console.log(jsonString); // Output: {"name":"Jane","age":25,"city":"Los Angeles"}

For handling large-scale JSON data processing, cloud services like Tencent Cloud offer scalable solutions. For instance, Tencent Cloud's COS (Cloud Object Storage) can store large JSON files, and services like Tencent Cloud Functions can be used to process these files as needed, providing efficient and flexible data handling capabilities.
