Well... go ahead and try installing JSR on your local machine. You can't, because JSR is a website. Let's do the inverse and try installing a package from pnpm.

Well... go ahead and try installing JSR on your local machine. You can't, because JSR is a website. Let's do the inverse and try installing a package from pnpm.io! You can't, because the only thing available for download on that website is pnpm itself. pnpm lets you download packages to your computer -- a "manager", if you will. JSR gives you a centralized place to find packages at -- a "registry", if you will. We use different words because these two things are not interchangeable and it's not just a JS thing.
