Scala Currying Function

In this tutorial, we will learn about currying functions in scala.Suppose, we have a function that has multiple arguments and this function can be transformed into series of functions where each function has single argument. This process is called currying function in scala.

Let’s understand this with help of examples. You see a currying function below which adds 2 values accepting as arguments.

Now, if we want to make it a curried function it will be written as given below. It accepts two list of one Int parameter each. When calling, we need to pass arguments in 2 separate enclosed brackets ().

We can create series of functions with single arguments and use underscore as placeholder for missing arguments. We can call those newly created function by passing missing whenever required.
