JS Sandbox Console

How to Use

This is a JavaScript playground/testing environment for experimenting with code: • Type JavaScript commands in the input box at the bottom and press Enter to execute them • Results appear above your input with a "=>" prefix • Use Up/Down arrow keys to scroll through your command history • Alt + Enter creates a new line for multi-line code blocks • Alt + Up/Down navigates history while in multi-line mode Special commands start with a colon: • :help - shows help information • :clear - clears the console output and history • :load [URL] - loads external JavaScript files into the sandbox The console evaluates code in real-time and displays: • Returned values and expressions • Error messages with basic syntax highlighting • Object data in readable format Your command history automatically saves and persists between sessions. The sandbox provides a safe environment to test JavaScript code, experiment with functions, and try out libraries without affecting the main page. Perfect for learning JavaScript, testing code snippets, or exploring new programming concepts interactively.
