Hanguly I created this simple web app for my first daughter. This web application is designed for learning Korean characters, specifically the Jamo system. Jamo refers to the basic building blocks of Korean characters. Ja (Ja-eum) represents consonants in the Korean writing system (e.g., b, k, c, and f in English). Mo (Mo-eum) represents vowels in the Korean writing system (e.g., a, e, i, o, and u in English). User Interface Simply drag and drop Jamo character buttons. A fun and easy way to learn the structure of Korean characters.
