How do I use default values with destructuring in JavaScript?

You can set default values in destructuring by using the assignment operator. For example: const { a = 1, b = 2 } = obj;.

What happens if the property is undefined?

If the property is undefined, the default value will be used. For instance, if obj has a as undefined, a will be set to 1.

Can I use default values with arrays too?

Yes! You can use default values with array destructuring like this: const [x = 10, y = 20] = arr;.

What if I want to skip some values in an array?

You can skip values by leaving the position empty. For example: const [,, z = 30] = arr; will skip the first two values.
