What is array destructuring in JavaScript?

What is array destructuring in JavaScript?

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

Can you give me an example of how to use it?

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

What if I only want the first two elements?

You can do that by using a comma: const [first, second] = arr; This will give you the first and second elements, while the third will be ignored.

Are there any common mistakes to avoid?

Yes! One common mistake is trying to destructure an undefined variable. Always ensure the array exists before destructuring.
