What is the difference in NodeJS between a package name with @ and without?

Question

Node.js

What is the difference between packages with and without the @ symbol in their names? For example, there is @babel/core and babel-core, but babel-loader exists in a single name. I have noticed that those packages that start with @ have a more recent version number than their aliases.

Previously, they were not there, now they are being switched to - for example, the same babel moved not so long ago, that's why it's fresh in @.
