How do I use object destructuring in JavaScript?

How do I use object destructuring in JavaScript?

Object destructuring allows you to unpack values from objects into distinct variables. For example, if you have an object like const person = { name: 'Alice', age: 25 };, you can extract the values like this: const { name, age } = person;.

Can you give me an example with nested objects?

Sure! If you have a nested object like const user = { id: 1, profile: { name: 'Bob', age: 30 } };, you can destructure it like this: const { profile: { name, age } } = user;.

What happens if the property doesn't exist?

If the property doesn't exist, the variable will be undefined. For example, if you try to destructure const { address } = person;, address will be undefined.

Can I set default values while destructuring?

Yes! You can set default values like this: const { name, age = 18 } = person;. If age is not present, it will default to 18.
