What are some real-world applications of map, filter, and reduce in programming?

Map, filter, and reduce are powerful functions in functional programming. For example, you can use map to transform a list of numbers by squaring each number.

Can you give me more examples of how to use filter?

Sure! You can use filter to extract even numbers from a list. For instance, if you have a list of integers, filter can help you get only the even ones.

What about reduce? How is it used in real-world scenarios?

Reduce is often used to aggregate data. For example, you can sum up all the values in an array or concatenate strings from a list.

Are there any libraries that utilize these functions?

Yes, many libraries like Lodash in JavaScript and Pandas in Python provide these functions, making data manipulation easier.
