Summary
This one's a lifesaver if you're building n8n workflows that need custom JavaScript logic. It handles the tricky bits like properly accessing webhook data under the `.body` property, returning the correct `[{json: {...}}]` format that trips up most people, and choosing between "Run Once for All Items" versus "Run Once for Each Item" modes. The skill covers real patterns like multi-source data aggregation, batch processing with SplitInBatches, and using built-ins like `$helpers.httpRequest()` and DateTime. Most useful when you need to transform data, make API calls, or do any custom logic that the standard nodes can't handle.
