Description

Comprehensive Angular 7 training covers all major topics required to fully use this next generation of the Angular framework. Angular 7 makes the creation of single page applications even easier than before. In this course developers will learn to use Angular Directives and to create Angular 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 Router. The course also covers everything you need to know about Typescript - a programming language based on JavaScript that is used to create Angular applications.

Lab exercises provide essential and practical hands-on experience for each topic.
