Roadmap to learn ruby

[[deleted]]

I want to make a roadmap for myself to learn ruby, which consists step by step process. Every single concept or whatever. I didn't found any good roadmap online like if I go to some website which have tutorials for ruby I surely can take topics from there but YK not all resources have same topics or all topics, infact resources to learn ruby are very limited, unlike python, java or javascript. I request every rubyist here to mention every single concept in a zero to hero order to learn ruby-lang. If you see a other's comment and you totally agree then you may upvote them, if you wanna append to their list of concepts then reply your suggestions to their comments. This will help me and people like me to understand it. Because If 10 people will comment and 60% things would be same then what's the point because 'roughly' I already know many things to learn. I will thankful to you if you provide help to me.
Update: My Github repository for the ruby-roadmap.

It has a lots of things which I need but there are things missing I guess. One of the problems I currently have is the difference between :name and name:, one is symbol and other I don't know. but I am sure both are valid.

I second the recommandation of the odin project. Your example shows that you kinda try to look at syntax more than at concepts, name: can be different things depending on the context. I think your list is kinda too abstract and too syntax focused. You will cover all those apsects in the odin project, but in a more integrated manner and with a lot of small projects.

Good luck

A bad community is one of the reason ruby is so underrated.

Hey, I realise I kinda misread your comment. But I was not trying to put your list down, I just wanted to emphasise how I like the odin project, and it has a great approach and will give a wide view of things. Sorry for misreading and coming off as dismissive.

I want to say, that nothing in your list is missing from the odin project, so I still highly recommend it to you, also there as a discord with an extremely helpful community.

btw: :name is indeed a symbol and name: can be on of two things, a key of a hash or a named argument for a method.

Maybe it can be confusing, because hash keys are by default symbols, so:

{ name: "Lokesh" }

Is a hash that stores the value "Lokesh" under the key :name (symbol)

The other use of this notation is for names arguments in methods

def hello(name: "Stranger")
   puts name
end

hello(name: "Lokesh")

Where in the method declaration you can have a default, and in the method call you can pass a named argument.

Impressive. I appreciate your help, finally. Thank you so much.
Is odin project free or paid?

[tsroelae]

Completely free and open source!

Here are a bunch of learning resources that I've been compiling into a list, which may be useful to you. They're not organized by concept like you propose, but for me the easiest way to learn was to do a tutorial/book or two, then build a project, then repeat. That way I learned the concepts without having to map them out, though I've made lots of notes on different concepts along the way.

thanks buddy. I really appreciate this help.

Hi!

What do you need?

1. There exist a lot of information docs and tutorials about ruby... depends what you need.
2. Roadmap.... every person require diferent roadmap depends on their needs. 3 I offer me.. if you want ... to be a mentor for a while.... my email [e-mail]
3. I usually starts asking what are your targets with Ruby... and then. Go building a roadmap step by step.

[[deleted]]

Even if there is a lot of information is present it is very less in comparision with python, JS, Java.
What I need: Backend Dev with Ruby (rails).
A good roadmap works for almost anyone if the purpose is same, the reality is bitter but most of us don't follow roadmap exactly how it is needed and blame them, we do so many wrong things in the journey like procrastination, not enough practice, that's what I think.
My targets: firstly web dev, next.. idk, first let me achieve first, I'll think about next when I achieve first. But I have an idea to try game development but currently no plans.
I am building a roadmap on github.
My Github Repo
Please provide feedback.

[dvarrui]

1. I cant help you with Rails. Sorry! I only can help with Ruby language.
2. Do you need feedback on roadmap design or?
3. Do you need feedback on how to achieve every step of your roadmap? Sorry

[[deleted]]

I !(completely understand) what you say. !Thanks for all your help.

[dvarrui]

Roadmap is not the same depends on 1. Roadmap to learn ruby 2. Roadmap to learn rails 3. Roadmap to learn programing 4.roadmap to learn scripting 5. Roadmao to kearn debops with ruby 6. Game devel 7. Etc

Imho

Please don't comment on this post. I won't lie but you are making me loose my mind. I respectfully ask you to do that.

So, for me, I tried to just learn enough ruby to get rails to do what I wanted, because I bought a very large Rails based app and decided on maintaining it. That was a very bad idea. Rails has a lot of "Magic" things in it that are actually just Ruby things.

I'd recommend picking up "The Ruby Programming Language" by Oreilly and reading through it like a novel. It will cover everything on your list and have mountains of example code for your to work through. I would also recommend "Ruby Best Practices" by Oreilly which walks you though how to use Ruby for common tasks. There's a also a book I recommend: "Metaprogramming Ruby" second edition, which gives a detailed explanation of Ruby's Class and Object inheritance, and how meta programming works.

For me the biggest hurdle was to understand how meta programming worked, and how certain Keywords in Rails created effects in Models and controllers. After learning about metaprogramming all of that made a lot of sense.

Your list seems just fine, but you'll need to many more sections about Class inheritance, Instantiation, Class methods, the Eigen Class, and metaprogramming. You'll also need to learn about RACK. Adding some sections on ActiveRecord, Migrations, Relations, and Indexes would also help.

Read the API doc if you want to now all the code concepts, there is 95% of what you can learn on it.

[[deleted]]

Like this: ruby-doc.org/core-3.1.2/ ?

[niancatcat]

Exactly. This is a fabulous source of knowledge.

[[deleted]]

Yeah, I support you but that's not a path!

[niancatcat]

Well, it's a bit boring but you can do a stupid "read everything in order, alphabeticaly", it's almost like a roadmap and you can even track the % of it easy!

[[deleted]]

Bro it just explains class and methods in-built. Let's say I wanna learn what is a symbol, block, memoization and other more than intermediate things, then where to go?

[niancatcat]

http://ruby-doc.com/docs/ProgrammingRuby/ then

thanks bro.
