What are some use cases for destructuring in JavaScript?

Destructuring in JavaScript allows you to unpack values from arrays or properties from objects into distinct variables. It's useful for cleaner code.

Can you give me an example of destructuring an object?

Sure! For example, if you have an object like const person = { name: 'Alice', age: 25 };, you can destructure it like this: const { name, age } = person;.

What about destructuring arrays?

For arrays, you can do something like const numbers = [1, 2, 3]; and then destructure it with const [first, second] = numbers;.

Are there any performance benefits to using destructuring?

While destructuring itself doesn't provide performance benefits, it can lead to cleaner and more maintainable code, which can indirectly improve performance by reducing errors.
