How do I handle undefined values in my code?

How do I handle undefined values in my code?

You can handle undefined values by using checks like 'if (value !== undefined)' or using default parameters.

What about using the nullish coalescing operator?

Yes, the nullish coalescing operator (??) is great for providing default values when dealing with null or undefined.

Can you give me an example of that?

Sure! For instance, you can write: 'let result = value ?? defaultValue;' which assigns defaultValue if value is null or undefined.

Are there any pitfalls I should be aware of?

Yes, be cautious with falsy values like 0 or '' as they won't trigger the nullish coalescing operator.
