How can I merge two JavaScript objects?

You can merge two JavaScript objects using the Object.assign() method or the spread operator. Which one would you like to know more about?

What's the difference between Object.assign() and the spread operator?

Object.assign() copies properties from source objects to a target object, while the spread operator creates a new object. The spread operator is often more concise.

Can you show me an example of using the spread operator?

Sure! Here's an example: const obj1 = { a: 1 }; const obj2 = { b: 2 }; const merged = {...obj1, ...obj2}; // merged is { a: 1, b: 2 }.

Are there any limitations to these methods?

Yes, both methods perform a shallow merge, meaning nested objects won't be deeply merged. You might need a library like Lodash for deep merging.
