When should I use map instead of filter in programming?

Can you explain when to use map instead of filter in programming?

Sure! Use map when you want to transform each element in a collection, and filter when you want to select elements based on a condition.

Can you give me an example of using map?

Of course! If you have an array of numbers and you want to double each number, you would use map like this: numbers.map(num => num * 2).

And what about filter? Can you show me that?

Certainly! If you want to get only the even numbers from an array, you would use filter like this: numbers.filter(num => num % 2 === 0).

So, map changes the data while filter just selects it?

Exactly! Map transforms the data, while filter narrows down the selection based on a condition.
