What are some advanced uses of the spread operator in JavaScript?

The spread operator (...) can be used for various advanced tasks, such as merging arrays, cloning objects, and even function arguments. Would you like examples of each?

Yes, please provide examples for merging arrays and cloning objects.

Sure! For merging arrays, you can do: const merged = [...array1, ...array2];. For cloning objects, you can use: const clone = {...originalObject};. This creates a shallow copy of the object.

What about using it with function arguments?

Great question! You can use the spread operator to pass an array as arguments to a function like this: myFunction(...myArray);. This spreads the elements of the array as individual arguments.

Are there any limitations to using the spread operator?

Yes, the spread operator creates shallow copies, so nested objects are still referenced. For deep cloning, you might need a different approach.
