How can I debug nested data issues in my application?

To debug nested data issues, start by inspecting the structure of your data. What specific problems are you encountering?

I'm getting undefined values when trying to access properties in a nested object.

Check if the properties you're trying to access exist at each level of the object. You can use console.log to trace the values.

I see that one of the properties is missing. How can I handle that?

You can use optional chaining (?.) to safely access properties without throwing an error if they are undefined.

That makes sense! Is there a way to validate the entire structure of the nested data?

Yes, you can use libraries like Joi or Yup to define a schema and validate your nested data structure.
