Issues have been encountered with the functionality of $rootScope

I am currently struggling with a code snippet in my loginCtrl.js file where I can't seem to get $rootScope to store the value of vm.userEmail.

app.controller('LoginCtrl', function($timeout, $q, $log, $rootScope /*$auth*/,   $location, $mdToast) {
    var vm = this;
    vm.loginMessage = '';
    vm.login = function(){
        $auth.login({
            $rootScope: vm.userEmail,
            password: vm.userPassword
    })  
  }
});

I believe using $rootScope would be beneficial for handling certain conditions when a specific user connects.

if ($rootScope == '<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="651c3a1c25d0d1108040c094b0608">[email protected]</a>') {
        data = [1,2,3,4]
    } else {
        data = [5,6,7,8]
    }

If you have any ideas, suggestions or corrections, please feel free to share them ;)

Think of $rootscope as a unique application context where you can add new values. Take a look at the code snippet below for an example of how it works:

app.controller('LoginCtrl', function($timeout, $q, $log, $rootScope /<em>$auth</em>/,   $location, $mdToast) 
{
    var vm = this;
    vm.loginMessage = '';
    vm.login = function(){
        $auth.login({
            $rootScope.userEmail : vm.userEmail,
            password: vm.userPassword
        })  
    }
});

You now have access to $rootScope.userEmail throughout the entire application.

If ($rootScope.userEmail == '[email protected]') {

    data = [1,2,3,4]
} else {
    data = [5,6,7,8]
}

rather than

$rootScope = someValue;

try

$rootScope.someValue= someValue;

For the second part of your code, attempt:

observe changes in $rootSchope.someValue

example:

$rootScope.$watch('$rootScope.someValue', function(newValue) {
    if (newValue='<a href="/cdn-cgi/l/email-protection" class="__cf_email__" data-cfemail="71082e0831191e051c10181d5f121e1c">[email protected]</a>') {
        data = [1,2,3,4]
    }
});
