An example of an AI chatbot conversation about when to use spread syntax in JavaScript.
When should I use spread syntax in JavaScript?
Spread syntax is useful for expanding elements in an iterable, like arrays or objects. It allows for easier manipulation.
Can you give me an example of using spread syntax with arrays?
Sure! You can use it to combine two arrays: const combined = [...array1, ...array2];.
What about using it with objects?
With objects, you can merge them like this: const merged = {...obj1, ...obj2};.
Are there any performance considerations I should be aware of?
Yes, while spread syntax is convenient, it can be less performant for large datasets compared to traditional methods.
