I purchased a number of classes that I will be going through to progress my knowledge on a number of topics. To build out a knowledgebase of my learnings I will be keeping this repository up to date, and tagged with each section as I progresss through the class.
Below are class notes that will be broken out by section, and lecture. Each section will be tagged so that the history of the repository, and it associated code can be preserved.

Takeaways
- vals are immutable therefore cannot be reassigned
- variables are mutable and can be reassigned

- prefer vals over vars
- all vals and vars have types
- compiler automatically infers types when omitted
- learned how to use basic types
- Boolean
- Int, Long, Double
- String
Takeaways
- Basic expressions: operators
- If in Scala is an expression
- Code blocks in scala are expressions
- The value of a code block is the value of it's last expression
- Expressions vs. Instructions
- Instructions are executed (think Java)
- Expressions are evaluated (Scala)
- Do not use while loops in your Scala code
