When should I use filter or map in JavaScript?

Can you explain when to use filter or map in JavaScript?

Sure! Use filter when you want to create a new array with elements that pass a test, and map when you want to transform each element.

Can you give me an example of using filter?

Of course! If you have an array of numbers and want to get only the even ones, you can use array.filter(num => num % 2 === 0).

What about map? Can you show me that too?

Certainly! If you want to double each number in an array, you would use array.map(num => num * 2).

So, can I use them together?

Yes, you can chain them! For example, you can first filter the even numbers and then map them to double their values.
