When should I use the spread operator instead of other methods?

The spread operator is great for expanding arrays or objects. It's concise and often more readable than methods like concat or Object.assign.

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

Sure! If you have an array let arr1 = [1, 2, 3]; and you want to add more elements, you can use let arr2 = [...arr1, 4, 5];.

What are the advantages of using the spread operator?

It simplifies code, avoids mutation of the original array or object, and improves readability.

Are there any situations where I shouldn't use it?

Yes, if performance is critical and you're dealing with very large arrays or objects, traditional methods might be more efficient.
