This repository contains intermediate JavaScript homework focused on:

• Loops and Iteration
• Functions

The exercises are designed to help students practice iteration logic, function structure, and basic algorithms using plain JavaScript.

⚠️ No array methods are allowed.

By completing this assignment, students will be able to:

• Write reusable functions
• Use loops to process data
• Iterate over arrays and strings
• Build simple algorithms step by step
• Improve logical thinking using JavaScript fundamentals
