Demo Code N Run

Purpose

Allows to execute embedded JavaScript code fragments on Commons pages. A code fragment is activated to become editable and executable by CodeNRun.js. A output textarea is added below the code to capture any text output (e.g. console.log("text")).

This allows for scripts to generate complex text for easy copy & pasting.

Warning

This is using eval() to execute in your browser context!
