Lucas and Luna dig into a common but invisible performance drain: unused npm dependencies. They walk through a real case where a startup's production bundle included 3,000 unused packages, adding 2MB to the JavaScript payload and slowing startup time by 1.2 seconds. They explain how tree-shaking fails with side-effect flags, how tools like depcheck and webpack-bundle-analyzer surface the bloat, and a practical workflow for keeping your node_modules lean. By the end, you'll know exactly how to audit your own project and cut the dead weight.
