What are advanced iterators in JavaScript?

Advanced iterators in JavaScript include methods like map(), filter(), and reduce(), which allow for more complex data manipulation.

Can you explain how the reduce() method works?

Certainly! The reduce() method executes a reducer function on each element of the array, resulting in a single output value.

What are some practical use cases for map() and filter()?

You can use map() to transform data, like converting an array of numbers to their squares, and filter() to remove unwanted elements, like filtering out odd numbers.

Are there any performance considerations when using these methods?

Yes, while these methods are convenient, they can be less performant than traditional loops for large datasets due to the overhead of function calls.
