want to check null values. any() method returns null or array of matched result (actually there's a match() method inside which is returned).

$scope.isMobileBrowser = !isMobile.any() ? false : true;

If any() method returns null I want false to be assigned to $scope.isMobileBrowser variable, otherwise true. will the over mentioned snippet fail in any probable case? Is there any other more efficient workaround?

for more details of isMobile object:

var isMobile = {

    Android: function() {

        return navigator.userAgent.match(/Android/i);

    },

    BlackBerry: function() {

        return navigator.userAgent.match(/BlackBerry/i);

    },

    iOS: function() {

        return navigator.userAgent.match(/iPhone|iPad|iPod/i);

    },

    Opera: function() {

        return navigator.userAgent.match(/Opera Mini/i);

    },

    Windows: function() {

        return navigator.userAgent.match(/IEMobile/i);

    },

    any: function() {

        return (isMobile.Android() || isMobile.BlackBerry() || isMobile.iOS() || isMobile.Opera() || isMobile.Windows());

    }

};
