Learn Ruby: 30 Best Ruby Tutorials for Programmers
Using irb, we will be able to test Ruby's basic syntax and directly view the result, without having to create a file containing our code a. The command prompt has changed.
You can now directly type your orders. Try typing the following lines:. Many things in this simple example.
We have just created two variables, a and b, and assigned them values. Then we decided to display their sum using the puts method. You will notice that nowhere have we defined the type of a or b.
Ruby manages like a big one: Short Description: In what follows, each item includes a reference to a section or code listing with an example of the change in question. Sec- tion 3.
Sec- tion 6. To accomplish this goal, the Ruby on Rails Tutorial takes an integrated approach: you will learn Rails by example by building a substantial sample application from scratch.
If you are used to skipping around in technical books, taking this linear approach might require some adjustment, but I suggest giving it a try. You can think of the Ruby on Rails Tutorial as a video game where you are the main character, and where you level up as a Rails developer in each chapter. The exercises are the minibosses. Fol- lowing the scaffolding approach risks turning you into a virtuoso script generator with little and brittle actual knowledge of Rails.
At each stage of developing the sample application, we will write small, bite-sized pieces of code—simple enough to understand, yet novel enough to be challenging.
There are also many web development shops that specialize in Rails, such as ENTP, thoughtbot, Pivotal Labs, and Hashrocket, plus innumerable independent consultants, trainers, and contrac- tors.
What makes Rails so great?
Rails also adapts rapidly to new developments in web technology and frame- work design. The comments below contain some suggestions for approaching the Rails Tu- torial depending on your background. The answer depends on your personal learning style and how much 1.
On the other hand, many beginning Rails developers are excited about making web applications, and would rather not slog through a page book on pure Ruby before ever writing a single web page.
In this case, I recommend following the short interactive tutorial at Try Ruby,2 and then optionally do the free tutorial at Rails for Zombies3 to get a taste of what Rails can do. Another common question is whether to use tests from the start.
Inexperienced programmers: The Rails Tutorial is not aimed principally at beginning programmers, and web applications, even relatively simple ones, are by their nature fairly complex. Experienced programmers new to web development: Your previous experi- ence means you probably already understand ideas like classes, methods, data structures, etc.
Ruby even lets you put semicolons at the ends of lines if you miss them too much. Experienced web developers new to Rails: You have a great head start, es- pecially if you have used a dynamic language such as PHP or even better Python.Try these math operations: You can think of the Ruby on Rails Tutorial as a video game where you are the main character, and where you level up as a Rails developer in each chapter.
