What's the value of currying in Functional Programming?

Question

I know the concept and how to use of currying, but I wonder what is its value in practice?

Answer 1

As the related question covers, Practical use of curried functions? , there are many reasons why people value currying and make use of it, including:

• improving code reuse -- special case functions are simply partially-applied (and curried) generic functions
• improving code readability -- map (+2) is easier to read than map (\x -> x + 2)
• improved performance -- currying can make obvious certain specializations, and a good compiler will generate the specialized version for you
• fun -- simpler code , more beautiful code makes life more enjoyable.
