What are some common iterator methods in JavaScript?

Common iterator methods in JavaScript include forEach, map, filter, reduce, and some. Each serves a unique purpose.

Can you explain how the map method works?

Sure! The map method creates a new array by applying a function to each element of the original array.

What about the reduce method? How is it different?

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

Can you give me an example of using filter?

Absolutely! The filter method creates a new array with all elements that pass the test implemented by the provided function.
