JavaScript Bundle Size, Privacy & Modern Patterns

This page collects 5 articles, newest first. Bundle size is the recurring theme here, because it's the one metric that quietly gets worse every sprint while everything else stays green. Alongside that: the ES2024+ additions genuinely worth adopting, the iterator helpers that remove a class of intermediate arrays, the array grouping methods, and the privacy footprint of location-aware code that most teams never audit. A few pieces revisit older ideas, like Rob Pike's rules of programming, and check whether they still hold up against modern JavaScript. Usually they do, which says more about the ideas than about the language. Nothing here assumes a framework, so it applies whether you're shipping React, Svelte, or plain modules.
