If you have been working with any node/javascript framework - be it React, Angular, Vue - there's an issue if you use npm or yarn.
It's something that happens in the background that you may not have noticed with every project you fire up - you redownload the packages in every instance.
What that means is that you end up having duplicates of the same packages in different folders on your machine.
I don't know about you, but I'm not okay with that...
Why PNPM?
Instead of redownloading the packages again, pnpm creates a central store where the packages are kept.
When you start up a new project, it checks if any of the packages required are already present on your system. If they are, it creates a reference to that store and doesn't redownload anything.

Why store separate copies of packages if you can have asinglereferencable one?
That's the idea behind PNPM which makes it a performant, space-efficient, and faster alternative to NPM/Yarn.
