An example of an AI chatbot conversation about array destructuring in JavaScript.
What is array destructuring in JavaScript?
Array destructuring is a syntax that allows unpacking values from arrays into distinct variables.
Can you give me an example of how to use it?
Sure! For example, you can do const [a, b] = [1, 2]; which assigns 1 to a and 2 to b.
What happens if the array has fewer elements than variables?
If there are fewer elements, the variables will be assigned undefined for the missing values.
Can I use default values in array destructuring?
Yes! You can set default values like this: const [a = 3, b = 4] = [1]; which assigns a to 1 and b to 4.
