Package Management practice
npm, yarn, and pnpm — dependencies done right
JavaScript package management the way the official docs describe it — how npm, yarn, and pnpm resolve, install, and lock dependencies; semantic versioning and version ranges (^, ~, and exact pins); the lockfile and why committing it matters; dependencies vs devDependencies vs peerDependencies; the scripts lifecycle and running them; workspaces and monorepos; the node_modules resolution model and pnpm’s content-addressable store; and publishing and supply-chain security (audit, provenance, lockfile integrity). Concept-first and evergreen, with a teaching explanation after every answer. Part of the Developer track.
