How do I choose between map and filter?

I'm trying to decide whether to use map or filter in my code. Can you help me understand the difference?

Sure! The map function is used to transform each element in a collection, while filter is used to select elements based on a condition.

So, if I want to double the numbers in an array, I should use map?

Exactly! Use map to apply a function to each element, like doubling them. Filter would be for selecting specific elements.

What if I want to get only the even numbers from an array?

In that case, you would use filter to create a new array that includes only the even numbers based on your condition.

Got it! Can I use both map and filter together?

Yes, you can chain them! First, use filter to get the elements you want, then use map to transform those elements.
