Introduction
In recent years web technologies became a silver bullet for cross-platform UI development. However we still have a lot of discussion on it pros and cons. The most critical issue developers face creating web apps is a performance comparing to native applications. A lot of "know how" needed in order to produce HTML / JS application which is as fast as iOS or Android native. Challenging Native workshop is a one day practical guide into web performance which cover all aspects you need to know in order to create fast applications and stunning interactive experiences able to challenge native platforms.
