What are the migration paths between them?

I can only answer questions about practical-tutorials/project-based-learning or trekhleb/javascript-algorithms.

The question about "migration paths between them" isn't clear in that context. Could you clarify what you mean? For example:

• Are you asking about code dependencies between the two repos?
• Are you asking about URL redirects tracked in practical-tutorials/project-based-learning's link-rot system?
• Are you asking about learning progression from one repository to the other?

Once you clarify, I can help answer with specific citations from the repository data.
