Ruby Assessement

Hello all! Since my last post I have been going over SQL, JQuery, and the Flatiron's school Ruby assessment. I really like doing the assessment because working ruby examples has let me know areas I am weak in. Tomorrow I plan on working more on SQL and the assessment. Till next time.

Modules, Hashes, and Classes

Today I learned about modules and testing in Ruby on Treehouse and on Codecacademy I learned more about Hashes and Classes. I also did some of the Extra Credit exercises on Treehouse. Some of the key things I learned today:

Modules

• Modules are similar to Classes, but modules only can use methods and constants. 
• Module uses extend and include to modify classes and objects.

Hashes and Classes

• Hashes can use symbols instead of strings to identify keys ex(:one => 1)
• We can convert symbols to strings and vice versa buy using the methods .to_sym and .to_s.
• We must use and initialize method in a class. It boots up the objects that the class creates.
• Can create and instance of a class by calling new on the class name. An instance variable is attached to the instance of that class hence its name.

Tomorrow I plan on going through Chris Pine's book "Learn to Program". That is all for now.

Arrays and Hashes

Hello all.  Today I have been learning about arrays and hashes on Code Academy.  Arrays and Hashes are used to store things. We can access the things in the arrays and hashes by using an index. Indexes in arrays start at 0. Indexes in arrays can be accessed by the key. Hashes are made up of key-value pairs (ex. pet => "Ben"). We can create empty hashes by using Hash.new. I also learned how to use the .each iterator with a hash. The syntax look like this: name_of_hash.each {|x| action}.  That's what I've learned so far today. Tomorrow I hope to continue learning Ruby on Code Academy and Treehouse.

Accepted into the Flatiron School!

Hello all.  On Friday October 11th I found out I was accepted into the Flatiron School Fellowship program. I'm really excited and I hope that I excel while I'm here. Since then I've been trying to get the prework done. Currently I'm doing the Ruby Foundations on Treehouse. I will also try to write a post daily. Until next time.
