Welcome back! You've already learned the basics of loops in Ruby and how to iterate through collections using for and each loops. Now, let's take it one step further. In this lesson, we'll explore loop controls, specifically break and next. These powerful tools give you finer control over your loops, making your code even more efficient and flexible.

In this lesson, you'll discover how to use break to exit a loop early and next to skip to the next iteration in a loop. These controls can make your loops more sophisticated and adaptable to different scenarios.

Here's a sneak peek at what we'll cover:

Let's break down the code for better understanding:

1. Initialization:

   • We create an array called shopping_list containing several items.
   • We set a variable max_items to 4, indicating the maximum number of items we want to process.
   • We initialize items_processed to 0 to keep track of how many items have been processed.

2. Loop Through Items:

   • The each method begins to iterate over each item in the shopping_list.

3. Break Condition:

   • The loop checks if items_processed equals .

Understanding how to control loops with break and next is vital for writing more effective and readable code. These commands empower you to:

• Exit loops early: Using break, you can stop a loop when a condition is met, saving time and resources.
• Skip iterations: With next, you can bypass specific cases within a loop, making your code cleaner and more efficient.

By mastering these loop controls, you'll be able to handle complex looping scenarios with ease, making your programs more robust and dynamic.
