With this in mind, we all want our applications to be faster, but how do we know what bottlenecks to focus on? This course will cover how to leverage various browser APIs to capture your application's live performance data, understand what the metrics mean, and focus on the ones you should really care about. Along the way you'll learn how to monitor real users, understand when to use synthetic testing tools, and automate performance tracking.
