Course Overview
I designed this course to help Java developers move toward idiomatic Ruby. I am not trying to teach Ruby as a pile of disconnected syntax rules. I want to show you why Ruby code often ends up smaller, more expressive, and more behavior-oriented than a direct translation from Java.
At the same time, I do not want this course to exclude anyone else. If you are coming from another language, you can still use it well. The Java comparisons are there because they make certain Ruby ideas easier to explain, not because Java is required.
The repository now contains fifteen topics and two appendices. That matters because this is no longer only a beginner syntax pass. I can now take you from foundations into object design, applied Ruby work, and more abstract transformations in one connected sequence.
What I Want This Course To Do
By the end of the course, I want you to be able to:
I am trying to build judgment as well as vocabulary. It is not enough to know that blocks, keyword arguments, mixins, and Enumerable exist. I want you to see when those tools make code better and when they make it harder to read.
How I Built Each Topic
Each topic uses a small set of teaching pieces:
The rhythm I have in mind is straightforward:
Even a tiny class becomes more interesting once you have to name it, test it, and decide how much behavior belongs in it.
How The Course Progresses
I find it helpful to think of the fifteen topics in four phases.
Topics 1 through 5 cover:
This is where Java habits show up most clearly. Many learners still write Ruby as though a compiler is standing over them. In this phase, I want you to stop asking "How do I translate this from Java?" and start asking "What makes the intent clear in Ruby?"
Topics 6 through 9 move into:
In this phase, I am no longer asking only what Ruby can express. I am asking where behavior should live, how collaborators should relate to one another, and how small design choices change the feel of the code.
Topics 10 through 12 apply Ruby to working problems:
These topics matter to me because they push the language into contact with state, files, persistence, and input formats. The design pressure becomes more realistic.
Topics 13 through 15 move into:
By the end of the course, I want you to be moving beyond recognition into fluency. You should be able to read a transformation and see not only what it does, but why that form was chosen.
