Web App Optimization

Optimisation is an unavoidable step in complex applications. The question is: At what stage of the application's lifetime it is done and at what cost?

By understanding what's behind the JavaScript engine, one can prevent performance issues by writing better javascript and avoid a big percentage of the optimisation phase.

In this talk we will learn about the JS engine, how it works and how it relates to runtime performance. We will then dive into practical examples from real life applications. Using live coding, we will see how to monitor and fix performance issues. By the end of this talk you will have the knowledge to solve common performance bottlenecks and monitor your app to easily debug.
