A then-representative $200USD device had 4-8 slow (in-order, low-cache) cores, ~2GiB of RAM, and relatively slow MLC NAND flash storage. Meanwhile, developer behaviour offers little hope: Median mobile JavaScript payloads have only grown since 2016, now hovering above 400KiB of script transferred, or nearly 2.5MiB of uncompressed JS.

In many organizations, front-end developers know exactly what common underlying problems are and what loading patterns should be used to fix them. So every time a conversation about further development happens, performance is a part of that conversation as well. Establish a performance culture. thanks, Guy Podjarny!

In many organizations, front-end developers know exactly what common underlying problems are and what loading patterns should be used to fix them. The former is particularly useful during development as it will help you identify, isolate and fix performance issues while working on the product. Establish a performance culture.
