When should I use filter instead of map in JavaScript?

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

Sure! Use filter when you want to create a new array with elements that pass a certain condition, while map is for transforming 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 filter like this: const evens = numbers.filter(num => num % 2 === 0);

What about map? Can you show me that too?

Absolutely! If you want to double each number in an array, you would use map like this: const doubled = numbers.map(num => num * 2);

So, filter is for conditions and map is for transformations?

Exactly! Filter is for selecting elements based on a condition, while map is for applying a function to each element.
