YAML is all about clean, readable nested structures. You can nest lists inside mappings, mappings inside mappings, and lists inside lists. It makes complex data feel simple and tidy.

💡 Pro Tip: Use consistent 2-space or 4-space indentation — no tabs — for clean nested structures.
📑 How Nesting Works
Mapping inside mapping: Indent under a key to nest a dictionary
List inside mapping: Use - under a key to list items
Mapping inside list: Indent key-value pairs under a - to nest mappings inside lists
🧠 Example: Mapping Inside List
📌 This lets you build arrays of objects cleanly. Super useful for things like server configs, user profiles, etc.
📚 Conclusion
YAML nesting is what makes it clean, minimal, and way easier to read than JSON. Use it for configs, manifests, and structured data whenever possible.
