Extends the destination object dst by copying own enumerable properties from the src object(s) to dst. You can specify multiple src objects. If you want to preserve original objects, you can do so by passing an empty object as the target: var object = angular.extend({}, object1, object2).
AngularJS has this built-in method for doing object to object copies called angular.extend(). It is a very powerful function that has many uses.
Let’s consider a mythical ThingController that looks like this using traditional AngularJS code:
app.controller(‘ThingController’, [ ‘$scope’, function($scope) {
$scope.thingOne = ‘one’;
$scope.thingTwo = ‘two’;
$scope.getThings = function() {
return $scope.thingOne + ‘ ‘ + $scope.thingTwo;
};
}]);

Lots of assignment to $scope to create member variables (models) and methods. This is how it would look if we used angular.extend():
app.controller(‘ThingController’, [ ‘$scope’, function($scope) {
angular.extend($scope, {
thingOne: ‘one’,
thingTwo: ‘two’,
getThings: function() {
return $scope.thingOne + ‘ ‘ + $scope.thingTwo;
}
});
}]);
Using angular.extend() seems like a cleaner way to express all these assignments to $scope. The only nit I have with this is that models and methods are mixed in some arbitrary order. We could clean it up with code looking something like this:
app.controller(‘ThingController’, [ ‘$scope’, function($scope) {
// models
angular.extend($scope, {
thingOne: ‘one’,
thingTwo: ‘two’
});
// methods
angular.extend($scope, {
// in HTML template, something like {{ getThings() }}
getThings: function() {
return $scope.thingOne + ‘ ‘ + $scope.thingTwo;
}
});
}]);

If you’re searching for a business app, React Native is a viable solution.When compared to native app development, you may release your app in less time and at a cheaper cost.
React Native is usually a good fit for most apps, unless it’s a fast-paced, graphically intense game when utilizing native code for Android or IOS has advantages.It has demonstrated its worth as a quick application development framework that is trustworthy, quick, and scalable by being used by firms such as Instagram, Facebook, and Tesla, among many others.
Take a peek at some of the mobile apps created with React Native App Development Services.In this blog, you will learn about the advantages of developing an app in React Native.There are several advantages to using React Native Mobile App Development Services in Australia1) Saves Time and MoneyBecause 95 percent or more of the code is cross-platform, meaning it is compatible with both Android and iOS, developers only need to write one app, resulting in the creation of two apps.
This saves time during app creation, which saves a lot of money that would have been spent on establishing individual apps.
Businesses may use React Native to develop two applications at the same time for less than half the cost of producing just one.
Furthermore, maintenance and upgrades are performed on both applications at the same time, saving money when the applications are constructed and deployed.2) Great PerformanceReact Native apps operate remarkably identically to native apps developed on the respective iOS or Android platforms.
