## Summary

JavaScript package managers make it easy to add dependencies, but the resulting tree can contain packages no one chose directly. Starting with `is-string`, this talk examines what gets installed and how to find packages that could be replaced by native code or lighter alternatives.

It introduces dependency inspection tools and e18e, a project focused on cleaning up and improving the JavaScript ecosystem. The talk also encourages developers to inspect their own projects before adding another package.
