6:00 - 7:30 PM


Jacob Richardson / IMT Group



We go back to basics this month and look at Ruby collections and the Enumerable module. Rubyists learn early on that as long as a class provides an 'each' method (and optionally a <=> comparison operator), simply mixing in the Enumerable module will automatically give the class all kinds of collection functionality including traversal, searching, sorting, etc.

Jacob will discuss the Enumerable module and also discuss

  • Increasing the readability of your code by reducing null checks and loops
  • Functional thinking applied with Enumerable
  • Extending Enumerable

Jacob currently works as a Python developer for IMT Group, but not for long. He has accepted a job as a Rails developer at GroupOn in Chicago and will be moving there soon. Earlier this year, Jacob was recognized as a Rails Up-and-Comer by Obie Fernadez. This will be Jacob's last Iowa Ruby Brigade meeting for a while, so please come out to wish him well.
