What are advanced destructuring techniques in JavaScript?

Advanced destructuring techniques allow you to unpack values from arrays or properties from objects into distinct variables. This can simplify your code and make it more readable.

Can you give me an example of array destructuring?

Sure! For example, 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 about object destructuring?

For object destructuring, consider const obj = { x: 1, y: 2 };. You can destructure it like this: const { x, y } = obj; Now x is 1 and y is 2.

Are there any nested destructuring techniques?

Yes! You can destructure nested objects or arrays. For example, const data = { user: { name: 'Alice', age: 25 } }; can be destructured as const { user: { name, age } } = data;.
