What are some practical use cases for map, filter, and reduce in programming?

Can you explain the use cases for map, filter, and reduce in programming?

Sure! Map, filter, and reduce are higher-order functions commonly used in functional programming. They help in processing collections of data.

What does the map function do?

The map function transforms each element in a collection based on a provided function, returning a new collection with the transformed elements.

Can you give me an example of using filter?

Absolutely! The filter function creates a new collection containing only the elements that satisfy a specified condition. For example, filtering out even numbers from an array.

And what about reduce?

Reduce takes a collection and reduces it to a single value by applying a function cumulatively to the elements. For instance, summing all numbers in an array.
