Partially-Applied Functions (and Currying) in Scala

WebOct 12, 2024 · One of the best ways to understand use cases for generic classes is to look at examples in the Scala standard library. Most Scala generic classes are collections, such as the immutable List, Queue, Set, Map, or their mutable equivalents, and Stack. Collections are containers of zero or more objects.

Currying and partial application make it possible to create smaller functions of differing behavior by applying some arguments to the curried function. Let’s make our sum function more generic by adding mapping function f: Int => Int, also known as the identity function, which will map both values before adding … See more In this tutorial, we’ll look at how Scala supports currying. We’ll see how it differs from the partial application function and the advantages of … See more Partial application is the process of reducing the number of arguments by applying some of them when the method or function is created. … See more Currying is the process of converting a function with multiple arguments into a sequence of functions that take one argument. Each function returns another function that consumes the following argument. See more Type inference takes into account only one parameter list at the time. That means that in some cases, we can help the compiler to derive the proper type. As an example, we’ll create a findmethod that returns the first element … See more WebScala Currying also makes it easier to pass around a function as a first-class object.
