When should I use map, filter, or reduce?

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

Sure! Use map to transform each element in an array, filter to remove elements based on a condition, and reduce to accumulate values.

Can you give me an example of using each of them?

Of course! For map, you might use it to double each number in an array. For filter, you could remove all odd numbers. For reduce, you could sum all numbers in an array.

What if I want to chain them together?

You can chain them! For example, you can filter an array first, then map the results to transform them, and finally reduce to get a single value.

Are there performance considerations I should be aware of?

Yes, chaining can be less performant due to multiple iterations. It's best to use them judiciously based on your needs.
