Pulls in tree shaking patterns to help you eliminate dead code from your JavaScript bundles. This is the skill to use when you're importing from libraries but only using a fraction of what they export, and your bundle size is bloating. It teaches ES2015 module syntax requirements, the difference between named and wildcard imports, and how to mark packages as side-effect-free in package.json. The content from patterns.dev does a solid job explaining how bundlers like webpack treat your code as a graph and traverse from entry points. One thing to internalize: side effects break everything, so understanding when imported code touches global scope matters more than you'd think.
