What is the performance difference between destructuring and spread in JavaScript?

Destructuring and spread are both useful in JavaScript, but they have different performance implications. Destructuring is generally faster for extracting values from arrays or objects, while spread can be more resource-intensive as it creates a shallow copy of the array or object.

Can you give me an example of each?

Sure! For destructuring, you might have: const {a, b} = obj;. For spread, you could use: const newArray = [...oldArray];.

Which one should I use for large datasets?

For large datasets, prefer destructuring when you only need specific values, as it's more efficient. Use spread when you need to create a new array or object.

Are there any scenarios where spread is better?

Yes, spread is better when you need to merge arrays or objects, as it allows for a clean and concise syntax.
