In Ruby, how do I skip a loop in a .each loop, similar to "continue"

💎 Ruby: Skipping a Loop in .each Loop

Hola amigos! 👋 Welcome to my tech blog, where I unravel the mysteries behind coding conundrums. Today, we'll tackle a common question faced by Ruby developers: how to skip a loop in a .each loop, just like using continue in other languages. 🚀

So, let's dive right in and explore the solutions to this problem, shall we? 💡

The Scenario

A fellow developer reached out, asking how to skip a loop iteration in Ruby. Imagine you're iterating over an array or collection using Ruby's trusty .each loop. But wait! 😱 You encounter a situation where you want to skip the current iteration and move on to the next item. What do you do? 🤔

The Easy Solution

Fear not, for a neat trick exists in Ruby to achieve this! Simply use the next keyword within the .each loop to jump to the next iteration, skipping the remaining code inside that iteration. It's like having a teleportation device for your loops! 🚀

Here's a quick example:

numbers = [1, 2, 3, 4, 5]

numbers.each do |number|
  next if number.even?
  puts number
end

In this example, we have an array of numbers. Using the .each loop, we iterate over each number. However, we want to skip and not display the even numbers. By adding next if number.even?, we can seamlessly navigate to the next iteration if the number is even. The output will only display the odd numbers from the array.

A Better Understanding

To further grasp the concept, let's break it down:

1. The .each loop iterates over each item in the numbers array.

2. The next keyword acts as a skip button, jumping to the next item, if necessary.

3. The condition if number.even? checks if the current number is even.

4. If the number is indeed even, the next keyword is triggered.

5. If the number is odd, the loop continues executing the remaining code block.
