When should I use map, filter, or reduce in JavaScript?

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

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

Can you give me an example of each?

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

What are the performance implications of using these methods?

Generally, map, filter, and reduce are efficient, but using them in a chain can lead to performance overhead. It's best to choose the right one based on your needs.

Are there any alternatives to these methods?

Yes, you can use traditional loops like for or forEach, but they may be less concise and readable compared to map, filter, and reduce.
