Sad that I missed RubyConf! Looking through tweets, I saw some pictures of job board. I very quickly wrote down everything I could make out in the hopes that a text version might be helpful to some.

The order is roughly in columns, left to right. If there is anything that's wrong or missing, please let me know and I'll change it. Thanks to @filipebarcos and this (tweet)[https://twitter.com/filipebarcos/status/1197201242700812288?s=09] as being my best source.

# Write a program that prints out the numbers 1 to 100 (inclusive). If the number is 
# divisible by 3, print Crackle instead of the number. If it's divisible by 5, print Pop. 
# If it's divisible by both 3 and 5, print CracklePop. You can use any language.

My Javascript Logic Recipie

I have found that the Javascript work we have done so far lends itself to encapsulate in logical steps. When starting new javascript work, here is the little cookbook/recipie I follow. Here are my thoughts using TicTacToe and PixArt as examples.

1) Datamodeling

I am going to define the object as the game. So that I can say myGame = new TicTacToe();

My game needs a board. It needs players, but X always goes first. And the game is either won or unwon but when it starts, there is no winner. I think my game should have how many moves have been played (but this could also be figured out by inspecting the board).

The actions I will have are only two: make a move, and see if someone has won.
