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 array with all elements that pass a test implemented by a provided function. For instance, filtering out even numbers from an array.

And how about reduce?

The reduce function executes a reducer function on each element of the array, resulting in a single output value. It's often used for summing values or accumulating results.
