Function composition is the technical term for your question.

Given 

def methodA(s: String): String = {
  s + ", hello "
}

def methodB(s: String): String = {
  s + " world!"
}

all the following function compositions evaluate to the same value

val a = methodA("Shyam")
methodB(a)

methodB(methodA("Shyam"))

(methodA _ andThen methodB)("Shyam")

(methodB _ compose methodA)("Shyam")

namely

Shyam, hello  world!
