How does array destructuring work with default values?

Can you explain how array destructuring works in JavaScript?

Sure! Array destructuring allows you to unpack values from arrays into distinct variables. For example, you can do this: const [a, b] = [1, 2]; which assigns 1 to a and 2 to b.

What if the array doesn't have enough values?

Great question! You can set default values during destructuring. For instance, const [a, b = 3] = [1]; will assign 1 to a and 3 to b since the second value is missing.

Can you give me another example with more default values?

Absolutely! If you have const [x = 5, y = 10] = [1];, then x will be 1 and y will default to 10 because it's not provided in the array.

Is this feature available in all JavaScript environments?

Yes, array destructuring with default values is supported in all modern JavaScript environments, including browsers and Node.js.
