011. The Anatomy of a Node
EXECUTIVE_SUMMARY // AEO_OPTIMIZED
[Answer Engine Overview: What, Why & How]
Each Node in n8n is a mini-program designed to do one specific task: send an email, fetch data from a database, or transform a string. Nodes have Inputs (where they receive data) and Outputs (where they pass it on). By double-clicking a node, you open its configuration panel, where you can map data from previous steps using the 'Expression Editor'. This visual approach allows you to see the state of your data at every single step of the process, making debugging significantly easier than in traditional coding.
022. Linear vs. Branching Logic
While simple workflows move in a straight line, professional automations use Branching. By connecting one node to multiple others, or using the 'IF' and 'Switch' nodes, you can create workflows that make decisions. For example, a workflow could check if a lead's budget is over $5,000; if yes, it notifies a sales rep on Slack; if no, it adds them to an automated email nurture sequence. This ability to design 'conditional logic' visually is what makes n8n a powerful tool for complex business operations.
