JavaScript Processing for Each Item

The Function Item node is fundamentally different from most n8n nodes:

• Processes each item individually using your custom JavaScript code
• Provides a pre-defined function structure with the item as a parameter
• Returns the processed item after your code executes
• Maintains access to all standard JavaScript methods and libraries
• Supports both synchronous and asynchronous operations

Key Technical Features:

• Pre-defined variables (item, $node, $items) for easier coding
• Full access to the item's properties for manipulation
• Ability to create entirely new data structures
• Support for try/catch error handling
• n8n-specific helpers for common operations

This JavaScript-powered approach gives you unprecedented flexibility in how you process and transform your workflow data.
