What are the different array iteration methods in JavaScript?

In JavaScript, common array iteration methods include forEach, map, filter, reduce, and some others. Would you like details on any specific method?

Can you explain how the map method works?

Sure! The map method creates a new array populated with the results of calling a provided function on every element in the calling array. It does not modify the original array.

What about the filter method?

The filter method creates a new array with all elements that pass the test implemented by the provided function. It's useful for removing unwanted elements.

How does reduce differ from the other methods?

The reduce method executes a reducer function on each element of the array, resulting in a single output value. It's great for accumulating values.
