Programming with Math (Exploring Type Theory)

If you are inventing a new language, start to study Type Theory.

These 3 are the same thing:

Logic = Category = Type

Unfortunately Milewski’s presentation was cut short due to time constraint, he only presented the first few “Type” functions:

  • Unit,
  • Product,
  • Sum,
  • Exponential,…

(these are from Category Theory refound in Type Theory).
