2025 JavaScript Beginner 1500 Problems D Conditional Statements

This is a practice-focused problem-solving course for JavaScript beginners. It consists of approximately 1,500 step-by-step problems that you can solve on your own, designed to help you naturally learn core concepts and internalize grammar.

Features of this course

📌 Over 1500 example problems → 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 basic grammar like conditionals, loops, and functions through examples. We aim for the feeling of "concepts become clear as you solve problems" rather than "learning concepts first."

📌 10% theory, 90% practice composition → Move your hands immediately after a brief explanation. Each problem is designed so you can run the code directly and verify that it works as intended.
