This repository is a Japanese language learning application consisting of two interconnected parts: a Jekyll-based static website and an Ionic/Angular hybrid mobile app. Both platforms share core educational content (lessons, vocabulary, grammar) stored in JSON/YAML/CSV files and provide features like furigana rendering, verb conjugation, spaced repetition flashcards, audio pronunciation, and multi-language support. The web version uses Gulp for asset processing and TypeScript for interactive components, while the mobile app leverages Ionic Framework v2 for native-like functionality. The application focuses on delivering structured lessons from the '新版中日交流标准日本语' textbook with JLPT N2 preparation goals.
