Introduction

Some features of the language

To get this to work I downloaded scala and intellij.

Some definitions

Immutability is when we can not allowed to change a variable. Not changing a value means parallelism will work better
Expression are something yields a value. e.g. x+y and have not side effects
Statements is code which does something. e.g. do(something) and have side effects
Function is a a relation between a set of inputs and a set of outputs with the property that each input is related to exactly one output.
- Pure always has the same output, easier to test, parallelisation
- Impure may not have the same output
High Order Functions are function which take functions as an argument

 I used https://shunsvineyard.info/2020/11/20/setting-up-vs-code-for-scala-development-on-wsl/ for installing with VS Code.
