# Tutorial - Mastering n8n Expressions Welcome! You know what JSON is. Now, let's learn how to use it. This workflow teaches you how to pull data from one node and use it in another using n8n's powerful expressions. What is an Expression? An expression is a small piece of code inside double curly braces {{ }} that gets replaced with a dynamic value when the workflow runs. It's the "glue" that connects your nodes. How to use this tutorial: 1. The first node, "Source Data", contains all the data we will use. Execute it once to see what's inside. 2. Follow the path from top to bottom. Each node is a new lesson. 3. Read the sticky note for each lesson, then look at the node's configuration and its output to understand the concept.
