Tree-shaking Memes

You install one tiny date formatting library and suddenly your node_modules folder is the size of a 747. Then you build your "tiny React app" and somehow it's still pulling in half the internet despite tree shaking supposedly removing unused code. Tree shaking is that magical build optimization that's supposed to eliminate dead code from your bundle. In theory, it only includes what you actually import. In practice? Well, your final bundle is still mysteriously 2MB because some dependency deep in the chain decided to import the entire lodash library for one function. The ratio here is painfully accurate. You start with a massive airplane hangar of dependencies, shake the tree real hard, and end up with... a slightly smaller airplane hangar. But hey, at least webpack says it's optimized.
