if defense of being old and grumpy

this..

taking poorly written code,
writing poorly written alternative,
but in less lines,
which now needs comments to decipher...

is not an argument.
it's a fallacy.

1.original.js

function login(user) {
  if (!user) {
    user = getFromLocalStorage('user');
  }
  if (user) {
    if (user.loggedIn && user.isAdmin) {
      navigateTo('dashboard');
    }
    else {
      navigateTo('unauthorized');
    }
  }
  else {
    navigateTo('unauthorized');
  }
}

2.author.js

function login(user) {
  // if the user is null, check local storage to
  // see if there is a saved user object there
  user = user || getFromLocalStorage("user");
  
  // Make sure the user is not null, and is also
  // both logged in and an admin. Otherwise, DENIED. 🌲
  user && (user.loggedIn && user.isAdmin)
    ? navigateTo("dashboard")
    : navigateTo("unauthorized");
}

3.me.js

function login(user = getFromLocalStorage('user')) {
  if (!user || !user.loggedIn || !user.isAdmin)) {
    navigateTo('unauthorized');
    return;
  }
  navigateTo('dashboard');
}
