Synchronously execute functions/load dependencies

loadDependencies.js

$scope.loadDependencies = function(arr){
    var deferred        = $q.defer();
    var arrLen = arr.length,i = -1;
    (function loadNext(){
        i++;
        (i < arrLen) ? arr[i](loadNext) : deferred.resolve();
    })();
    return deferred.promise;
};

usage

var dep = [
function(next){
    setTimeout(function(){
        console.log('1');
        next();
    }, 1000);
},function(next){
    setTimeout(function(){
        console.log('2');
        next();
    }, 1000);
},function(next){
    setTimeout(function(){
        console.log('3');
        next();
    }, 1000);
}];

$scope.loadDependencies(dep).then(function () {
	console.log('finished loading');
});
