Why's (Poignant) Guide to Ruby Ruby in Twenty Minutes Introduction This is a small Ruby tutorial that should take no more than 20 minutes to complete. It makes the assumption that you already have Ruby installed. (If you do not have Ruby on your computer install it before you get started.) Interactive Ruby Ruby comes with a program that will show the results of any Ruby statements you feed it. Open up IRB (which stands for Interactive Ruby). If you’re using macOS open up Terminal and type irb, then hit enter. irb(main):001:0> Ok, so it’s open. Type this: "Hello World" irb(main):001:0> "Hello World" => "Hello World" Ruby Obeyed You! What just happened? irb(main):002:0> puts "Hello World" Hello World => nil puts is the basic command to print something out in Ruby. Your Free Calculator is Here Already, we have enough to use IRB as a basic calculator: irb(main):003:0> 3+2 => 5 Three plus two. irb(main):004:0> 3*2 => 6 Next, let’s try three squared: irb(main):005:0> 3**2 => 9 In Ruby ** is the way you say “to the power of”.

The Best Way to Learn Rails I come from a PHP background, but these days, I'm a full-time Rails developer. The difficulty for most people who make the switch lies in the learning curve that’s involved. Once you've become proficient in a language or framework, switching to a new one feels like an unnecessary (and time-consuming) challenge. However, learning Ruby and Rails is actually pretty easy! It's an incredibly powerful framework, and has a huge community pushing it along. This article details a full lesson plan that will get you up and running in no time! You might think learning Ruby is the most important step, and this is probably the part where everyone stops learning and just sticks with their current framework. Work through the Try Ruby exercises. The most recommended tool for dipping into Ruby's syntax is the Try Ruby website. Once you’ve worked through these exercises a couple of times, you'll have a solid base. Run gem install rails to install Rails. Next, you need to install Rails. Great!
