How do map, filter, and reduce compare in performance?

The performance of map, filter, and reduce can vary based on the context. Generally, map and filter are faster for transforming and filtering arrays, while reduce can be slower due to its more complex operations.

Can you give me an example of when to use each?

Sure! Use map when you want to transform each element in an array, filter when you need to select elements based on a condition, and reduce when you want to aggregate values into a single result.

What about their time complexity?

All three methods have a time complexity of O(n), where n is the number of elements in the array. However, the actual performance can depend on the specific implementation and the operations being performed.

Are there any scenarios where one is significantly better than the others?

Yes, if you need to perform multiple transformations or filters, chaining map and filter can be more efficient than using reduce, which may require more overhead.
