What are the benefits of using map, filter, and reduce in programming?

Using map, filter, and reduce can make your code more concise, readable, and expressive. They allow for functional programming techniques that can lead to fewer bugs and easier maintenance.

Can you give me an example of how each of them works?

Sure! For example, map transforms each element in an array, filter selects elements based on a condition, and reduce aggregates values into a single result. Would you like to see code examples?

Yes, please provide code examples for each.

Here's a quick overview:

1. Map: const doubled = numbers.map(num => num * 2);
2. Filter: const evens = numbers.filter(num => num % 2 === 0);
3. Reduce: const sum = numbers.reduce((acc, num) => acc + num, 0);

These methods can greatly simplify data manipulation!

What are some common use cases for these methods?

Common use cases include data transformation, filtering out unwanted data, and aggregating results, such as calculating totals or averages.
