Even though some of the chapters present basic concepts in front-end development the book is more about medium and advanced programmers. It's a collection of 10+ curated articles published on krasimirtsonev.com/blog. "10 Lessons in Front-end" we'll show you ES6 features, Flux design pattern, animations in HTML or how to smoothly run your application in 60 frames per second. You'll learn about the dependency injection in Angular or string-to-dom-element trick in jQuery. The book is not the typical step-by-step tutorial. It forms a wonderful mix of interesting topics by touching different front-end technologies.
