6 Hours of Coding Timetable for Beginners ⤵️ 📌 Session 1: Learning (2 hours) 🎯 Purpose: Build foundational knowledge by learning new concepts. Structure: 1 hr 30 min: Learn new topics through tutorials, documentation, and taking notes. 30 min: Hands-on practice with small exercises or examples to apply what you just learned. Break: Take a 20-30 min break to rest and recharge. 📌 Session 2: Experimentation (2 hours) 🎯 Purpose: Reinforce learning with targeted practice and experimentation. Structure: 1 hr: Solve coding exercises or challenges related to the day’s topic (e.g., beginner-level problems on HackerRank or CodePen). 30 min: Modify or experiment with variations of the examples to deepen understanding. 30 min: Build a small feature/component related to the topic (e.g., creating a simple form, manipulating the DOM). Break: Take another 20-30 min break to refresh your mind. 📌 Session 3: Project Work (2 hours) 🎯 Purpose: Integrate what you've learned by contributing to a real-world project. Structure: 1 hr 30 min: Work on a personal project aligned with your learning goals (e.g., building a simple calculator, creating a personal portfolio site, integrating an API). 30 min: Review and refactor your code, add comments for better readability, and reflect on what you've accomplished. Sample Routine Overview ⤵️ 🔻 First Hour (Learning): Dive into new topics, taking notes and gaining a conceptual understanding. 🔻 Second Hour (Practice): Tackle exercises and coding challenges to apply your knowledge. 🔻 Third Hour (Project): Apply what you've learned in a real-world context by working on your project.
