Q&A Network · Accepted Answer

To safely parse a JSON string in JavaScript and handle potential errors, you can use a try-catch block around the JSON.parse method. This ensures that if the JSON string is incorrectly formatted, the error is caught and handled gracefully.


        
        const jsonString = '{"name": "John", "age": 30}'; // Example JSON string

        try {
            const data = JSON.parse(jsonString);
            console.log("Parsed data:", data);
        } catch (error) {
            console.error("Error parsing JSON:", error.message);
        }

ADDITIONAL COMMENT: - The "try" block attempts to parse the JSON string using "JSON.parse". - If the JSON string is valid, the parsed object is logged to the console. - If the JSON string is invalid, the "catch" block catches the error and logs an error message. - This approach prevents your application from crashing due to unhandled exceptions. ✅ Answered with JavaScript best practices.
