🚀 What I Did

• Title case conversion using for loops and maps.
• Inventory Management.
• Codewars.

🧠 What I Learned

• Boolean - converter function.
• boolean - data type.

typeof true   // "boolean"
typeof false  // "boolean"

Boolean(10)      // true
Boolean(0)       // false
Boolean("hi")    // true
Boolean("")      // false
Boolean(null)    // false
Boolean(true)    // true

Class

• class is just a blueprint for creating objects.

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.

• module - provides a powerful way to organize and structure js.

import anyName from './module.js';

🔥 What’s Next

• mini projects.
• theory.
