I am new to REST and Angular JS.
What is the prerequisite to fully understand and follow the contents of the video course.
Would you suggest any book for understanding the basics of REST and Angular JS or can I start accessing the material directly with the starter class ?
The material is 9 hours long for exactly this reason - it covers the introductory stuff first. So - no - there's no need to have any AngularJS knowledge. You do of course need to know Java though although the Spring part is also started qlmost from scratch.
