Data Types
Also known as: types
Categories that classify data values and determine which operations can validly be performed on them. Understanding types prevents errors and enables correct operations.
💡 Intuition
Different kinds of data (numbers, text, true/false) work differently.
Core Idea
Operations depend on type: you can add numbers, concatenate strings.
🔬 Example
🎯 Why It Matters

⚠️ Common Confusion
'5' (text) and 5 (number) are different—some languages convert automatically, some don't.
