The output terminal displays console output, runtime errors, and execution results as you work. Standard output and standard error are color-coded for easy distinction.
Generate shareable links for collaboration, download code as files, and keep examples tidy with the file tools. Avoid sharing secrets or private credentials in snippets.
The integrated AI assistant panel offers inline code suggestions, explanations, and refactoring help. Use sample code when asking for help with private or sensitive projects.
Power users can enable Vim mode for full modal editing — Normal, Insert, Visual, and Visual Line modes with all standard motions (h/j/k/l, w/b/e, gg/G), operators (d/c/y), text objects (iw, i", a{), and Ex commands (:w, :q, :s). Emmet is also available for rapid HTML/CSS expansion with Tab-triggered abbreviations.
