Introduction to finding problems on your website or JavaScript back-end and some ways to fix them.

Here we will talk about many of the different performance problems that you may encounter in a JavaScript application. We will discuss front-end issues such as large file downloads, slow processing, and finding bugs. On the back-end we will discuss scaling across threads and servers using techniques like clustering and micro-services, writing asynchronous code, and dealing with sessions.

Most importantly we will be covering how to use data to identify performance issues that matter allowing you to choose what to ignore, what code to modify, and what just needs more hardware.
