Currying refers to the process of transforming a function that originally takes two parameters into a new function that takes one parameter. The new function returns a function that takes the original second parameter as its parameter.
Example
First, we define a function:
def add(x:Int,y:Int)=x+y
Then, when we apply it, we should use it like this: add(1,2)
Now, let's transform this function:
def add(x:Int)(y:Int) = x + y
def add(x:Int,y:Int)=x+ydef add(x:Int)(y:Int) = x + y
