Code IDE vs React Handbook

Code IDE brings a complete programming environment to your iPhone and iPad. Write, compile, and run code in 50+ languages — including Python, Java, C++, and JavaScript. Your built-in AI Agent autonomously plans, builds, and debugs entire projects for you. AUTONOMOUS AI CODING AGENT Your AI Agent handles complete project workflows — from scaffolding to debugging: • Auto-Build Projects — Describe what you want. The AI creates the full folder structure, files, and boilerplate automatically. • PLAN Mode & AUTO Mode — Review a detailed technical blueprint before execution, or let the agent run end-to-end autonomously. • AI Debugging — The agent scans your file tree, pinpoints logic errors, and applies patches automatically. • AI Memory — The agent remembers your coding style and project context across sessions for a personalised experience. • Human-in-the-Loop — Granular permission settings and approval prompts mean the AI never acts without your consent. PROFESSIONAL MOBILE IDE A desktop-class code editor and compiler designed for mobile: • Fast Compiler — Instantly compile and run Java, Python, C++, HTML, JavaScript, Kotlin, Rust, Go, and 40+ more. • Live Web Preview — Build and preview HTML, CSS, and JavaScript apps with real-time rendering. Visualise data with Mermaid Diagrams, 3D graphics, and charts. • Smart Code Editor — Syntax highlighting, auto-indent, bracket matching, code completion, pinch-to-zoom, and multi-tab editing. • Advanced File Explorer — Manage, move, and organise large multi-file codebases like a desktop IDE. • Workspace Sync — Import local projects and access your workspace directly from the Files app. • Template Gallery — Start new projects instantly with ready-to-run code templates. • Themes & Fonts — Fully customisable editor with high-contrast developer themes and fonts. 50+ PROGRAMMING LANGUAGES • Popular — Java, Python, C++, HTML5, CSS3, JavaScript • Mobile & Systems — Kotlin, C, C#, Swift, Rust, Go • Web & Scripting — TypeScript, PHP, Ruby, Shell, Lua • Data & Docs — JSON, XML, Markdown, Mermaid, Visual Basic, and more LOCALISED IN 19 LANGUAGES English, Arabic, Bengali, German, Spanish, French, Hindi, Indonesian, Italian, Japanese, Korean, Dutch, Polish, Portuguese (Brazil), Russian, Turkish, Ukrainian, Vietnamese, and Chinese (Simplified).
