What are some advanced techniques for array destructuring in JavaScript?

Advanced array destructuring can include nested destructuring, default values, and rest parameters. Would you like examples?

Yes, please provide an example of nested destructuring.

Sure! For instance, if you have an array like const arr = [1, [2, 3], 4];, you can destructure it like this: const [a, [b, c], d] = arr; This assigns 1 to a, 2 to b, 3 to c, and 4 to d.

That's helpful! How about using default values?

You can set default values in destructuring. For example: const [x = 10, y = 20] = [1]; Here, x will be 1 and y will default to 20.

What about using rest parameters with destructuring?

You can use rest parameters to collect remaining elements. For example: const [first, ...rest] = [1, 2, 3, 4]; Here, first will be 1 and rest will be [2, 3, 4].
