How can I parse a JSON string in JavaScript and handle potential errors?

Answer

To parse a JSON string in JavaScript and handle potential errors, you can use the "JSON.parse" method within a "try...catch" block. This allows you to catch any errors that occur during parsing.

<!-- BEGIN COPY / PASTE -->
        const jsonString = '{"name": "John", "age": 30}';

        try {
            const parsedData = JSON.parse(jsonString);
            console.log(parsedData.name); // Output: John
        } catch (error) {
            console.error("Invalid JSON string:", error.message);
        }
        <!-- END COPY / PASTE -->

Additional Comment:

Use "JSON.parse" to convert a JSON string into a JavaScript object.
Wrap the "JSON.parse" call in a "try...catch" block to handle any syntax errors in the JSON string.
In the "catch" block, you can log or handle the error as needed.
