In most computer systems, definition of performance is straight forward enough: do more work per time with less resources. For a frontend web application, this is rarely the case. Frontend applications not only need to be resource-efficient, but must also ""feel"" efficient to the user. This makes performance on the frontend mostly a user experience issue. Join me as we take a deep dive into the important performance metrics of a modern frontend app, how to measure them, and how to optimize them for both the machine and the user.
