Getting Started with Ruby Tutorial
If you’re new to programming and looking to learn a versatile and beginner-friendly language, look no further than Ruby! Ruby is a powerful and elegant language that is widely used for web development, automation, and more.
In this tutorial, we’ll walk you through the basics of getting started with Ruby. By the end of this tutorial, you’ll have a solid foundation in Ruby programming and be ready to start building your own projects.
Installing Ruby
The first step to getting started with Ruby is to install it on your computer. Ruby is easy to install and is available for Windows, Mac, and Linux operating systems. You can download the latest version of Ruby from the official Ruby website.
Hello World
Once you have Ruby installed, let’s start with a classic “Hello World” program. Open your favorite text editor and create a new file called hello.rb
. In this file, type the following code:
puts "Hello, World!"
Save the file and open your terminal. Navigate to the directory where you saved hello.rb
and run the following command:
ruby hello.rb
You should see the output Hello, World!
printed to your terminal. Congratulations, you’ve just written your first Ruby program!
Variables and Data Types
In Ruby, variables are used to store data. Variables in Ruby are dynamically typed, meaning you don’t have to specify the data type when declaring a variable. Here’s an example of how to declare and use variables in Ruby:
name = "Alice"
age = 30
puts "My name is #{name} and I am #{age} years old."
In this example, we declare two variables name
and age
and then print out a string using string interpolation to insert the variable values.
Control Structures
Ruby supports various control structures like if
, else
, and while
loops. Here’s an example of how to use an if
statement in Ruby:
age = 25
if age >= 18
puts "You are an adult."
else
puts "You are a minor."
end
Conclusion
This tutorial covered the basics of getting started with Ruby, including installing Ruby, writing a “Hello World” program, working with variables and data types, and using control structures. Ruby is a fun and powerful language to learn, and we hope this tutorial has inspired you to dive deeper into Ruby programming. Happy coding!
