We are uncovering better ways of developing software by doing it and helping others do it. Through this work we have come to value:

  • Functions & Types over classes
  • Purity over mutability
  • Composition over inheritance
  • Higher-order functions over method dispatch
  • Options over nulls

That is, while there is value in the items on the right (except for nulls), we value the items on the left more!

If you do not know what any of the above are and you are doing development, I would recommend finding them out
