Why should I profile the site on my phone?

Chances are, you are developing your site on a fast laptop or a desktop machine. Mobile phones on the other hand are much more resource constrained: slower CPUs, less RAM and GPU memory, higher connection latencies, and so on. As a result, you should always try to profile and debug your site on mobile hardware to get a better and closer picture of how your users will experience your site on their handset.

What is Chrome Canary and why should I use it?

Chrome Canary is the developer version of Chrome. It looks and acts like the regular Chrome browser, but it includes new and experimental features that haven't been released yet. We recommend analyzing websites with Canary to take advantage of the latest tech. However, be warned that Canary isn't guaranteed to be stable, so expect crashes and occasional bugs.

Follow your instructors!
