Loops in Ruby — Because Repeating Manually Is So 2000s | CodeCraft Diaries #4 Loops in Ruby — Because Repeating Manually Is So 2000s Imagine being told to print “I love Ruby” 100 times by hand. Sounds painful, right? Well, that’s what we used to do before loops existed (not really, but you get the point 😉). In today’s edition of CodeCraft Diaries , we’ll explore the magic of loops in Ruby — tools that make repetition effortless, elegant, and DRY (Don’t Repeat Yourself). Why Loops Matter Loops allow your code to execute a block repeatedly based on a condition or a set number of times. They're essential when you're handling lists, user input, data processing, and more. 1. while Loop The while loop runs as long as the condition is true . i = 0 while i Common mistake: Forgetting to increment the loop variable, which causes an infinite loop. 2. until Loop Think of until as the opposite of while — it runs until the cond...

Control Flow in Ruby — Teaching Your Code to Make Decisions 🧭 CodeCraft Diaries #3: Control Flow in Ruby — Teaching Your Code to Make Decisions “If coffee exists, drink it. Else, panic.” Congratulations, you just wrote your first decision in Ruby. Control flow is what gives your program a brain. It's how you get it to choose a path, evaluate a condition, and respond differently depending on what’s happening. 🌱 It Starts With a Question In real life, we make decisions constantly: If it’s raining, take an umbrella. If your code runs, you celebrate. Else, you debug 😭. In Ruby, we do the same using keywords like if , elsif , else , and unless . 🔄 If / Else in Action weather = "rainy" if weather == "sunny" puts "Wear sunglasses 😎" elsif weather == "rainy" puts "Take an umbrella ☔" else puts "Check the weather app 🤷" end Output: Take...
