Angular 4 training covers everything you need to know to get started with this next generation of the Angular framework. Angular 4 makes the creation of single page applications even easier that before. In this course, developers will learn to use Angular 4 Directives and to create Angular 4 Components and Services to develop applications based on the Model-View-Controller (MVC) architecture. You will learn to use HTML Templates to define views and to connect views with code using output, two-way, event and property bindings. The course reviews the benefits and challenges of Single Page Applications and how to overcome those challenges using the Angular 4 Router. The course also covers everything you need to know about Typescript – a programming language based on JavaScript that is used to create Angular 4 applications. Lab exercises provide essential and practical hands-on experience for each topic.
