Course Summary
Dan Wahlin3:31a year ago

Gain a solid understanding of the Angular framwework 💪

By learning Angular you'll greatly increase your chances of getting a job as a front-end developer! So in this course, the well-known Angular expert Dan Wahlin will teach you the framework through building a real-world application.

The course is split into several sections. In the introduction, you'll learn about the app you'll be building and the concepts you'll learn. Next up, you'll learn about components and modules, before we continue on with data binding. Then you'll learn about services and http and finally routing.

Throughout the course you'll be building an app which displays customer orders. Wahlin has chosen this project carefully, as it'll teach you all the core concepts behind Angular. So be prepared for 36 value-packed screencasts.
