angular.JS Training & Certification
The Google authorized Android Development course is primarily designed for programmers who want to learn how to create mobile applications on the Android platform. As a part of this course, you will create widgets, Customize List view, Grid view, Spinners etc, create applications using audio, video and sqlite database and finally publish it on Google Play. This course will help you learn mobile app development from scratch and unlock new job opportunities for you in start-ups as well as large organizations. Master Android app development, learn how to set up Android Studio, understand Android architecture in detail, learn about integrating your mobile apps with Facebook, Twitter and other social media, Google Drive, Google Maps, SQLite and learn how to create and optimize app user experience.
AngularJS is a structural framework for dynamic web apps. It lets you use HTML as your template language and lets you extend HTML’s syntax to express your application’s components clearly and succinctly. AngularJS’s data binding and dependency injection eliminate much of the code you would otherwise have to write. And it all happens within the browser, making it an ideal partner with any server technology. AngularJS is what HTML would have been, had it been designed for applications. HTML is a great declarative language for static documents. It does not contain much in the way of creating applications, and as a result building web applications is an exercise in what do I have to do to trick the browser into doing what I want?
In AngularJS, a Component is a special kind of directive that uses a simpler configuration which is suitable for a component-based application structure. This makes it easier to write an app in a way that’s similar to using Web Components or using the new Angular’s style of application architecture.
Angular distinguishes components from services to increase modularity and reusability. By separating a component’s view-related functionality from other kinds of processing, you can make your component classes lean and efficient. Ideally, a component’s job is to enable the user experience and nothing more. A component should present properties and methods for data binding, in order to mediate between the view (rendered by the template) and the application logic (which often includes some notion of a model). A component can delegate certain tasks to services, such as fetching data from the server, validating user input, or logging directly to the console. By defining such processing tasks in an injectable service class, you make those tasks available to any component. You can also make your app more adaptable by injecting different providers of the same kind of service, as appropriate in different circumstances.
Angular comes with some common pipes, like date and upper case and lower case. You can also write your own pipes to handle custom scenarios that fit your application needs. Pipes are a great way to change data in a reusable way, without having to embed the transform logic within component classes and without having to modify the data just for display purposes.
As you already know, an Angular project is made up of templates, components, services, and modules. They all run inside what’s known as the Angular environment. While it’s possible to write isolated tests, you won’t really know how your code will interact with other elements within the Angular environment. Luckily, we have several technologies that can help us write such unit tests with the least amount of effort.
