ReactJS Editor

This tool provides a browser-based code editor built on ReactJS that enables editing, running, and prototyping code projects without local tooling. It focuses on JavaScript/TypeScript, JSX, HTML/CSS, with patterns for multi-file projects, modules import, and package-like dependencies. It supports syntax highlighting, error spotting, auto-complete hints, and a sandboxed runtime to execute code safely.
The core logic maintains an in-memory multi-file project workspace, applies language modes, and relies on a safe sandbox to run code with isolated access. It exposes outputs such as console logs and execution status, enabling quick feedback during teaching demos or debugging sessions.
Unique value comes from immediate in-browser prototyping, simple sharing, templates, and a lean feature set that avoids full IDE complexity while preserving essential editing, running, and exporting capabilities. Ideal users include learners practicing fundamentals, mentors delivering live demonstrations, and developers testing small snippets without configuring a local environment.
