Terminal commands:
ls  Lists contents of current directory
cd <name>   Changes directory to one specified by name

Repository: a folder/directory with a Git monitoring it.

git remote add origin https://github.com/TheAlacrity/git-story.git    Bash command that creates the address for git-story repository.
git push origin master    Bash command that sends the repository to GitHub.

After git init, make changes, git add --all, git commit -m "message of changes", git remote add origin URL, git push origin master, make changes, git add --all, git commit -m "message", git push origin master...etc.

Rubyists prefer interpolation to concatenation for creating strings. Interpolation

Hash, Array, are classes in ruby. A class is a combination of what an object can do (behaviors) and what an object is (attributes).

Week 1, Day 3

Reader methods are used to access instance variables.
Instance variables are contained to a particular instance of an object (e.g. *that* chair; not chairs in general).

Objects are combinations of attributes and behaviors. Behaviors in Ruby are methods.

Reader methods (getter methods); writer methods (setter methods).

r + tab in sublime will add the attr_reader method (e.g. attr_reader :first_name)

composition (if it's a class), module (if not a class)--a list of behaviors to mix in to other classes, mix ins (act of using module)

Modules can be very useful for creating DRY code (removes redundancy of code)

Since modules are a list of behaviors, some coders believe it should not include redundant initialize method attributes (however, some coders do include the initialize method). An alternative is to create a parent class with initialize that includes the module of behaviors, then have the subclasses inherit from the parent class.

Main subject: APIs and the web

How does the web work?--Starts with a web request (where you type in the URL). Sends message from our computer through a series of tubes to the server.

http = hypertext transfer protocol

Responds primarily with html, css, and javascript (only responses from a web request)

Main subject: Rails

Rails is a framework for Ruby that is designed for building websites faster.

Ruby was made in 1995 by Someone Matsumoto. A man named David Henemeier Hansson (github.com/dhh  <-- He goes by DHH) built Rails in 2005. (He did not create github. Github does run off of Rails, however.) Hulu, AirBnB, and some other famous applications all run on Rails.

"If anyone tells you that Rails does not do big applications, they are lying." -Josh Nixon, circa 2019

@message = params[:message_1]

the syntax for adding key value pairs using params is URL?key=value&key=value&key=value&key=value  <- this would create 4 key value pairs
