What is the spread operator in JavaScript?

How do I use the spread operator to combine two arrays?

You can combine two arrays using the spread operator like this: const combined = [...array1, ...array2]; This creates a new array with elements from both.

Yes, absolutely! You can use it to merge objects as well: const merged = {...obj1, ...obj2}; This will combine the properties of both objects.

What are some common use cases for the spread operator?
