A English to Tigrinya dictionary for students
# English–Tigrinya Web Dictionary Engine
A minimalist, high-performance web dictionary application engineered to load, index, and query dual-language vocabulary files instantly on the client side.
## Features
- **In-Memory Data Architecture:** Fetches structural JSON dictionary entries asynchronously and indexes subentries via localized JavaScript `Map` and `Set` collections for fast lookup speeds.
- **Instant Search Processing:** Executes prioritized runtime word-matching logic (exact, starts-with, contains, and cross-definition checks) as the user types.
- **Client-Side Persistence:** Integrates browser `localStorage` streams to save individual word bookmark sets and user interface visual preferences.
- **Security & Reliability:** Employs explicit string escaping utilities to guard against client-side injection anomalies and sets up a standard Service Worker for baseline platform availability.
## Technical Stack
- **Frontend Core:** HTML5, CSS3 Custom Properties, Vanilla JavaScript (ES6)
- **Data Format:** Asynchronous static JSON structure
