Next.js application developer
Learn React before App Router structure, server boundaries and public page delivery.
Your goal
Publish a meaningful course page and handle invalid input and missing resources.
Use each checkpoint as evidence: solve an exercise without the solution open, explain its edge cases, and revisit a failed concept the next day. Course completion records practice; it is not an accredited qualification.
