`npm` and `pnpm` are both package managers for the Node.js ecosystem, but they have some differences:

1. **Efficiency**: `pnpm` is more efficient than `npm` in terms of storage and installation speed. `pnpm` uses a content-addressable filesystem to store all files from all module directories on a single location on the disk. It then links the files into the `node_modules` directories of your projects.

1. 2. **Strictness**: `pnpm` creates a more strict `node_modules` structure. It only creates symlinks to the locations where the packages actually reside in the global store. This can help catch missing dependencies that might not be caught with `npm`.

3. **Concurrency**: `pnpm` uses concurrent operations for various tasks to make the installation process faster.

4. **Compatibility**: `npm` is the default package manager for Node.js and is compatible with all packages, while `pnpm` might have issues with some packages due to its strictness.

In summary, if you want a more efficient and strict package manager, `pnpm` might be a better choice. If you want maximum compatibility and don't mind the extra disk usage, `npm` might be a better choice.
