Description

In recent years, web technologies became a kind of a "silver bullet" for UI and cross-platform development, but the attitude towards this issue is still not univocal.

Performance issues compared to native application is one of the main problems faced by developers when creating web applications. Lots of know how are needed in order to create a HTML/JS application, which will be as fast as IOS or Android Native. 

During this course, you will learn techniques that will enable you to develop high performance web applications, improve UI responsiveness making your users even happier. 

"Performance optimization is not just about making your own application faster. Also we will be talking about the implementation of those things you could not do before..." — Challenging Native.
