Programming Paradigms
Programming languages are tightly coupled with the Von Neumann architecture. Functional programming is a way to decouple this dependency. It's also good for scalable computing.
Elements of Programming
SBT: scala build tool
call-by-name vs call-by-value. CBV evaluates all values first, CBN does substitution first.
Evaluation Strategies and Termination
CBV termination → CBN termination but CBN termination !→ CBV termination
Scala uses CBV but you can force CBN with =>
Conditionals and Value Definitions
if (a) b else c
but it's more like ternary.
