What are iterable methods in JavaScript?

Iterable methods in JavaScript are functions that allow you to iterate over data structures like arrays, strings, and maps.

Can you give me some examples of iterable methods?

Sure! Common iterable methods include forEach, map, filter, and reduce. Each serves a different purpose.

How does the map method work?

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

What is the difference between forEach and map?

forEach executes a function on each element but doesn't return a new array, while map returns a new array with transformed elements.
