Can you give me some real-world examples of destructuring in JavaScript?

Sure! Destructuring allows you to unpack values from arrays or properties from objects into distinct variables. For example, if you have an object like const person = { name: 'Alice', age: 25 };, you can use destructuring like this: const { name, age } = person;.

That makes sense! Can you show me an example with arrays?

Absolutely! For an array, say you have const colors = ['red', 'green', 'blue'];, you can destructure it like this: const [firstColor, secondColor] = colors; which assigns 'red' to firstColor and 'green' to secondColor.

What about nested objects? Can you provide an example?

Of course! For a nested object like const user = { id: 1, profile: { name: 'Bob', age: 30 } };, you can destructure it like this: const { profile: { name, age } } = user; to get name and age directly.

Thanks! This is really helpful.
