🎯 Learning Objectives

By the end of this class, students will be able to:

• Understand what loops are and why we use them.
• Use for, while, and do...while loops effectively.
• Use break and continue to control loop flow.
• Identify and fix infinite loops.
• Write small programs using loops for real-life scenarios.

🧠 1. What Are Loops?

A loop lets you run a block of code multiple times — until a condition is false.

Without loops, you’d have to repeat the same code again and again!

📘 Example (Without Loop):

console.log("Hello");
console.log("Hello");
console.log("Hello");
console.log("Hello");
console.log("Hello");

😩 Boring, right?

📘 Example (With Loop):

for (let i = 1; i <= 5; i++) {
  console.log("Hello");
}

✅ Cleaner, faster, easier to update.

🔹 2. The for Loop

Used when you know exactly how many times something should repeat.

📘 Syntax:

for (initialization; condition; increment/decrement) {
  // code to repeat
}
