+// &#128204; JavaScript Intermediate - Arrays and Objects
+
+// Welcome to the first section of the JavaScript Intermediate tutorial!
+// Here, you'll learn how to work with arrays and objects more efficiently.
+
+// Arrays - Ordered collections of values
+let fruits = ["Apple", "Banana", "Cherry"];
+console.log("Fruits:", fruits);
+
+// Accessing elements
+console.log("First fruit:", fruits[0]);
+
+// Adding and removing elements
+fruits.push("Orange"); // Adds at the end
+console.log("After push:", fruits);
+fruits.pop(); // Removes last element
+console.log("After pop:", fruits);
+
+// Iterating over arrays
+fruits.forEach((fruit, index) => {
+  console.log(`Fruit ${index + 1}: ${fruit}`);
+});
+
+// Objects - Collections of key-value pairs
+let person = {
+  name: "Alice",
+  age: 25,
+  city: "New York",
+};
+console.log("Person:", person);
+
+// Accessing object properties
+console.log("Name:", person.name);
+console.log("Age:", person["age"]);
+
+// Adding and modifying properties
+person.job = "Engineer";
+console.log("Updated person:", person);
+
+// Object iteration
+for (let key in person) {
+  console.log(`${key}: ${person[key]}`);
+}
+
+// &#128161; Practice working with arrays and objects using different methods!
