+// 📌 JavaScript Basics - Data Types
+
+// Welcome to the second section of the JavaScript Basics tutorial!
+// Here, you'll learn about different data types in JavaScript.
+
+// 🔍 What are Data Types?
+// Data types define the kind of value a variable can hold in JavaScript.
+
+// JavaScript has 8 basic data types:
+
+// String - Represents text values
+let name = "John";
+console.log("String:", name);
+
+// Number - Represents both integer and floating-point numbers
+let age = 25;
+let price = 19.99;
+console.log("Number:", age, price);
+
+// Boolean - Represents true or false values
+let isStudent = true;
+console.log("Boolean:", isStudent);
+
+// Undefined - A variable that has been declared but not assigned a value
+let address;
+console.log("Undefined:", address);
+
+// Null - Represents an intentional absence of value
+let phone = null;
+console.log("Null:", phone);
+
+// Object - A collection of key-value pairs
+let person = {
+  firstName: "Alice",
+  lastName: "Smith",
+  age: 30,
+};
+console.log("Object:", person);
+
+// Array - A special type of object that holds a list of values
+let colors = ["red", "green", "blue"];
+console.log("Array:", colors);
+
+// Symbol - A unique and immutable value (used for object properties)
+let id = Symbol("id");
+console.log("Symbol:", id);
+
+// 💡 Practice creating variables using these data types.
