call second function once the first function execution is completed

I have 2 functions, say A() and B(). I want to call function B() after the function A() execution is completed. and I dont want to write the the function B() calling inside the definition of function A(), because function A() is used in other modules too and that take unnecessary. I am trying to call function A() first and then once it is done then call function B(). because function B() uses function A() $scope variable

I use .then() but its giving error .then() undefined something. I called function B() inside function A() that works but i don't want that way.

$scope.fetchApplicantData();  //function A()
$scope.fetchMobileMessages($scope.ApplicantMicroDetails.AD_I_PASTEMP_RESI_CONTACT_NO);    //function B()

I am expecting to call function A() first once it is done call the function B(). because function B() uses function A() variable, but is don't want to call function b() inside the definition in function A()

You can use Promises like this: 

var promise1 = new Promise(function(resolve, reject) {
  setTimeout(function() {
    resolve('foo');
  }, 300);
});

promise1.then(function(value) {
  console.log(value);
  // expected output: "foo"
});

console.log(promise1);
