💡Key Points

  • Learn all beginner grammar areas including variables, conditionals, loops, and functions through problem-solving

  • Step by step, one problem at a time, natural progression from concepts → application → practice

  • A hands-on practice workbook where you learn by solving problems directly rather than conceptual explanations

The Features of This Course

📌 Over 1,500 practice problems → This is a practice-centered JavaScript beginner's guide where you learn concepts by solving problems. It focuses on learning by 'moving your hands directly' rather than simple memorization.

📌 Each problem serves as a concept guide → Structured to help you internalize beginner-level grammar such as conditionals, loops, and functions through examples. Rather than "learning concepts," the aim is for you to feel that "concepts become clear as you solve problems."

📌 10% theory, 90% practice → Brief explanations followed by immediate hands-on work. Each problem is designed so you can run the code directly and verify that it works as intended.
