Covers transitions/animations for both the JavaScript and CSS side of things, emphasizing (rightly so) the CSS side. It's so hard to find thorough, current articles online for Angular animations, and this book gives you just that. I was able to put many examples to use right away and get past issues that had me stuck for weeks on an aspect of a project at work. The book also goes in-depth by helping you to understand the performance aspects and see which commonly chosen properties animate slow, while offering alternatives that will make the animations more efficient. jQuery is not left out in this book either and in most sections where animation techniques are taught there are alternative implementations showcased that make use of jQuery. It's a great tutorial as well as a great reference, and one of the few books on Angular published in the last several months that won't feel dated when Angular 2.0 is finalized.
