scala - Apply several transformation functions to string -

suppose have 2 methods:

def a(s: string) = s + "..."  def b(s: string) = s + ",,,"  

and want create 3rd method call both methods:

def c (s: string) = a(b(s)) 

how can in idiomatic scala way?

i think it's better aggregate functions list , sequentially apply them:

list(a_, b_)

i think it's better aggregate functions list , sequentially apply them.

you specifying expected type:

scala> val fs: list[string => string] = list(a,b) fs: list[string => string] = list(<function1>, <function1>)  scala> fs.foldleft("something")((s,f) => f(s)) res0: string = something...,,,
