Question

Q&A Network · Accepted Answer

To convert a JavaScript object into a JSON string, use the "JSON.stringify()" method. To convert a JSON string back into a JavaScript object, use the "JSON.parse()" method.


        // Convert JavaScript object to JSON string
        const obj = { name: "Alice", age: 30 };
        const jsonString = JSON.stringify(obj);

        // Convert JSON string back to JavaScript object
        const parsedObj = JSON.parse(jsonString);

ADDITIONAL COMMENT: - "JSON.stringify(obj)" converts a JavaScript object into a JSON string. - "JSON.parse(jsonString)" converts a JSON string back into a JavaScript object. - Ensure the JSON string is well-formed; otherwise, "JSON.parse()" will throw an error. - Use these methods for data serialization and deserialization, especially when working with web APIs. ✅ Answered with JavaScript best practices.
