Time to read code
Ready to actually look at Ruby code? Don't worry, we'll keep it tiny and clear. 👀
Meet puts
The word puts simply tells Ruby to print something on the screen. That's it, no magic.
Your first line
Here it is in action. Run it and watch Ruby say hello back to you!
puts "Hello!"What are quotes for?
The quotes wrap your text. Anything inside the quotes is words for the computer to show as-is.
Storing a value
You can label a value with a name. Think of it like a sticky note on a box you'll use later.
See a name in action
Here we save a name, then print it. Notice how readable each line stays.
name = "Sam"
puts nameRuby reads top to bottom
Ruby runs your lines in order, top to bottom, just like reading a list of steps. Calm and predictable.
No clutter needed
Notice there's no weird punctuation cluttering things. Ruby keeps lines clean so you can focus.
You can read Ruby
See? You just read real Ruby and understood it. That's a genuine coding skill, and you have it. 🎉
