Ruby Blocks — The Secret Sauce Behind Elegant Code Ruby Blocks — The Secret Sauce Behind Elegant Code Picture this: You're writing Ruby. Things are going well… until you find yourself copying the same chunk of logic again. And again. And… wait, again? 😩 Enter: Ruby Blocks — your new BFF for clean, DRY, and elegant code. If methods are the skeleton of Ruby, blocks are the juicy muscles that flex logic in powerful ways. 🍱 Blocks? Like, Tupperware Blocks? Exactly! Ruby blocks are like code Tupperware — you can pack them with logic, pass them around, and execute them on demand. They're anonymous chunks of code that you can hand over to a method to be called later. 🔍 Syntax: The Two Faces of Ruby Blocks 1. Curly Braces for the Quickies: [1, 2, 3].each { |num| puts num } 2. do...end for Multiline Zen: [1, 2, 3].each do |num| puts "Double trouble: #{num * 2}" end Both are blocks. One's espresso; the other's a cappuccino. ...

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).

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...
