#try ruby

Работаем с переменными, знакомимся с типом данных “string” и конкатенацией строк (it is not fatal).

Давайте запустим терминал и войдем в режим irb:

irb    # вводим и жмем Enter

Поместим строку с именем нашего друга в переменную:

name = “Peter”    # Enter

=> "Peter"    # тип данных “string”

Теперь поприветствуем его используя конкатенацию строк:

“Hello, #{name}!”    # Enter

=> Hello, Peter!

Любую переменную, которую мы поместили внутри фигурных скобок #{name}, мы можем вызвать внутри строки.

Закрепим знания:

Создайте три переменных - имя животного, известного человека и название предмета. 

man = "lama"    # Enter => "lama" 

thing = "box"    # Enter => "box" 

animal = "cat"    # Enter => "cat"

Напишите предложение с использованием этих переменных.

"#{man} keep #{animal} in the #{thing}"    # Enter => "lama keep cat in the box"

Поместите предложение в переменную.

a = "#{man} keep #{animal} in the #{thing}"    # Enter => "lama keep cat in the box"

Используя метод “upcase” превратите все буквы предложения в заглавные.

a.upcase    # Enter => "LAMA KEEP CAT IN THE BOX"

In my opinion, every person in the world with half an hour of free time should go to Try Ruby.  It teaches you the basics of programming Ruby in a cute and not at all boring context.  I think it's a good way to realize how useful programming is and can maybe also give you some motivation to try it out.

I've been lagging behind a little bit in my studies, and I've only finished Try Ruby since my last post (whoops).  I'm considering just buying a monthly Code School subscription because all of their learning programs are colorful and have cute, fun themes.  Also, they have badges, which is kind of fun, and I've been too lazy lately, so any form of motivation helps.  

I'm writing this post a bit late because frankly, I forgot to write it on Sunday.  At this point in the program, Ruby has become my challenge.  I've been determined to not let it defeat me, lol.

Funny thing is, even though day by day I think I'm not learning anything, I actually am making a lot of progress.  I noticed it yesterday when I started working on Code School's Rails for Zombies course.  

I remember when I had worked on that course some months ago, I thought it was too difficult.  In fact, I though even Try Ruby was confusing.  But now, because my Ruby knowledge has greatly increased, those tutorials are much easier to understand for me. 

After almost four weeks in this program, I have personally found that working through online tutorial sites like Codecademy and Code School are not enough to teach me how to program, but they are a required prerequisite (in my opinion) to understanding the lectures and assignments that we get at the Iron Yard.

Everything we've been assigned for homework and projects in Ruby so far have been over my head.  All because I didn't have enough of a foundational Ruby background in order to be able to tackle the more advanced work that we get in the program.

So every day I've had to play catch up by going back and doing nearly every tutorial that I could find online.  And like I said at the beginning of this post, I was beginning to feel as though I wasn't learning anything, but I actually am.

When you are a true beginner, you hear the information differently than when you listen to it again with some knowledge.  It's weird.
