Can you explain array destructuring?

Can you explain array destructuring?

Sure! Array destructuring is a syntax in JavaScript that allows you to unpack values from arrays into distinct variables.

Can you give me an example?

Of course! For instance, if you have an array like const arr = [1, 2, 3];, you can destructure it like this: const [a, b] = arr; Now a is 1 and b is 2.

What if I want to skip some values?

You can skip values by leaving the corresponding positions empty. For example, const [first, , third] = arr; will give you first as 1 and third as 3.

Can I use it with default values?

Yes! You can assign default values like this: const [a = 10, b = 20] = arr; If arr doesn't have a value for a, it will default to 10.
