You have more ways to handle functions in a Array. Any Function can include Into a Array. Array allowed all Types. Best way is to Use a pattern principel. Its a Use Case:

Want Array to handle manipulations of Data before Service called.
I Use Class Syntax for faster Sample:
Class Ainterceptor {
intercept(data){ // Do your Manipulation and Return Data }
}

Class Service{
constructor(interceptors: [new AInterceptor()])}
setUser(data){
interceptors.forEach(i => data = i.intercept(data)
saveUser(data)
}
}
