What are the performance differences between Object.assign and the spread operator?

What are the performance differences between Object.assign and the spread operator?

Both Object.assign and the spread operator are used to copy properties from one object to another, but their performance can vary based on the context.

Can you explain how each method works?

Sure! Object.assign copies properties from source objects to a target object, while the spread operator creates a new object by spreading properties from existing objects.

Which one is faster in large data sets?

In general, Object.assign can be faster for large data sets, but it depends on the specific use case and the JavaScript engine.

Are there any limitations to using either method?

Yes, Object.assign does not handle deep cloning, while the spread operator can only shallow copy properties.
