What is the performance impact of the spread operator in JavaScript?

What is the performance impact of the spread operator in JavaScript?

The spread operator can be less performant than traditional methods, especially with large arrays or objects.

Can you explain why it might be slower?

It creates shallow copies of arrays or objects, which can be costly in terms of memory and processing time.

Are there any scenarios where it's better to use the spread operator?

Yes, it's great for merging arrays or objects and improving code readability, even if it has some performance costs.

How does it compare to other methods like concat or Object.assign?

The spread operator is often more concise and easier to read, but methods like concat or Object.assign can be faster in specific cases.
