Code Arena

About this project

Code Arena is a competitive coding platform built with Next.js, React, and TypeScript, exported as a fully static site — no backend. It ships 200+ challenges across 20 difficulty levels in five tiers, spanning algorithmic categories (arrays, dynamic programming, graphs, trees, backtracking) and language- or domain-specific tracks (C, C++, Rust, Python, TypeScript, React, network, security, SQL). The code editor supports 8 languages: JavaScript and TypeScript run locally in the browser, while C, C++, Python, Go, Rust, and Java are compiled and executed via the Wandbox API. The signature feature is CodeBot_9000, an AI opponent that issues sarcastic remarks at idle, on time thresholds, on code patterns, and on test pass/fail across seven moods. Progress is persisted to localStorage with a scoring formula of 100 points plus a speed bonus. The interface includes podium leaderboards, daily streak tracking, holographic 3D tilt cards, and a luxury gold-on-black theme.
