Junior Next.js Developer Roadmap

In this article, I describe a developer's skill levels using terms like Familiarity, Knowledge, Understanding, Deep Understanding, Ability, Proficiency, and Mastery.

  1. Familiarity: You've aware of the concept or tool and have used it in actual projects, but you're not yet comfortable with how everything works.
  2. Knowledge: You understand the basic ideas and some more complex parts, but there's still more to learn, especially about the most advanced features.
  3. Understanding: You have a solid understanding, including some of the more complex aspects. You're able to solve common issues and can explain how things work to others.
  4. Deep Understanding/Ability: You have expert-level knowledge and can identify the pros and cons. You're adept at applying this knowledge to a variety of projects.
  5. Proficiency: You have a high level of skill and can use the concept or tool effectively and efficiently.
  6. Mastery: You have an outstanding level of expertise, with a deep and comprehensive understanding that enables you to innovate and teach the subject.
