This in-class WOD assessed your ability to use the Underscore library.

Discussion:

  • Results are a little strange because I decided to only count the first to two problems. Good news: everyone was able to accomplish the first problem. Bad news: no one completed the second problem. I think that my expectations were too high for what you could assimilate after working with Underscore for only a a week. Many of you struggled to understand the concept of passing a function as an argument. This will become natural to you in time.
