File Handling in Ruby — Reading, Writing, and What Could Go Wrong File Handling in Ruby — Reading, Writing, and What Could Go Wrong CodeCraft Diaries #9 • For Freshers, Students & Curious Developers “If you’ve never accidentally deleted a file while testing your script, are you even a developer?” Working with files is one of the first real-world things you’ll do in any programming language. Whether it's reading a config, logging errors, or saving user data — file I/O is everywhere. And Ruby? Ruby makes it refreshingly simple. Until you forget to close the file... 💀 📖 Reading from a File Let’s say we have a file called data.txt . File.open("data.txt", "r") do |file| puts file.read end What’s happening here?

Ever copy-pasted a method from one class to another and thought: “I’ll clean this later...” Spoiler: You won’t. 🙃 That’s where **Modules** and **Mixins** come in — Ruby’s way of letting you *share code like a pro*, without inheritance spaghetti or duplicate soup. 🤝 What Is a Module?

Let’s be real: loops are the bread and butter of programming. But in Ruby? You don’t just butter the bread — you toast it, drizzle it with honey, and serve it like a gourmet dev snack. Welcome to the elegant world of Ruby iterators — where looping is expressive, concise, and kinda beautiful. 🚶 Why Not Just Use a Loop? You can, of course: for i in 1..3 puts i end But Ruby gives us cooler tools. Imagine replacing that clunky loop with something like: (1..3).each { |i| puts i } Cleaner. Readable.
