New Adventures in Front-End, 2021 Edition
summary
Argues that modern front-end complexity comes from device and network fragmentation: low-end phones like moto g4 behave 20–40× slower than modern iPhones, interactive buttons can take 15–25 seconds to become clickable on those devices. Recommends strict performance budgets (170 KB for slow networks, ~345–750 KB for faster ones) and profiling real user extensions (Dark Reader adds ~25s CPU). Shows component-driven workflows, AirBnB-style ML for recognizing/sketch→React generation, and recommends adaptive component shipping by connectivity and memory.
