auth2_services.js

const OAUTH2_OPTIONS = {
  facebookLogin() {
    // do the oath2 procedure for FB
  },
  googleLogin() {
    // do the oath2 procedure for google
  },
  instagramLogin() {
    // do the oath2 procedure for instagram
  }
}

function dispatchSocial(social) {
  const valid_socials = ["facebook", "google", "instagram"]
  
  if (valid_socials.includes(social)) { // validate social argument before execution
    OUATH2_OPTIONS[social + "Login"]() // calling the logins method dynamically here
  }
}
