+# Devlog - 2025-12-03
+
+## 🚀 What I Did
+
+- Title case conversion using for loops and maps.
+- Inventory Management.
+- Codewars.
+
+## 🧠 What I Learned
+
+- Boolean - converter function.
+- boolean - data type.
+
+```javascript
+typeof true   // "boolean"
+typeof false  // "boolean"
+
+Boolean(10)      // true
+Boolean(0)       // false
+Boolean("hi")    // true
+Boolean("")      // false
+Boolean(null)    // false
+Boolean(true)    // true
+```
+
+### Class
+
+| Use Case            | Better Choice |
+| ------------------- | ------------- |
+| Object blueprints   | ✅ `class`     |
+| Utilities / helpers | ✅ `function`  |
+| Modern projects     | ✅ `class`     |
+| Legacy code         | ✅ `function`  |
+
+- class is just a blueprint for creating objects.
+
+```javascript
+class Car {
+  constructor(name, speed) {
+    this.name = name;
+    this.speed = speed;
+  }
+}
+
+const car1 = new Car("BMW", 120);
+const car2 = new Car("Audi", 150);
+```
+
+- constructor runs automatically when you create a new object.
+- properties - variables that belong to the object.
+- methods - function inside a class.
+- this - means this current object.
+
+| Use Case               | Use Class? |
+| ---------------------- | ---------- |
+| Many similar objects   | ✅          |
+| Game characters        | ✅          |
+| API models             | ✅          |
+| Data structures        | ✅          |
+| One small object       | ❌          |
+| Simple helper function | ❌          |
+
+- `module` - provides a powerful way to organize and structure js.
+
+```javascript
+
+import anyName from './module.js';
+```
+
+## 🔥 What's Next
+
+- mini projects.
+- theory.
