What are some advanced object features in JavaScript?

JavaScript offers several advanced object features like object destructuring, spread/rest operators, and computed property names. Would you like to know more about any specific feature?

Can you explain object destructuring?

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

What about the spread operator?

The spread operator (...) allows you to expand an iterable (like an array or object) into its elements. For example, you can merge two objects: const obj1 = { a: 1 }; const obj2 = { b: 2 }; const merged = { ...obj1, ...obj2 }; results in `{ a: 1, b: 2 }.

Are there any other features I should know about?

Yes! Computed property names let you use expressions as property names. For instance, const key = 'age'; const person = { [key]: 25 }; creates an object with a dynamic key.
