21. Passing Your Lambda to a Method


crew = {
captain: "Picard",
first_officer: "Riker",
lt_cdr: "Data",
lt: "Worf",
ensign: "Ro",
counselor: "Troi",
chief_engineer: "LaForge",
doctor: "Crusher"

Add your code below!

first_half = lambda{|x, y| y < "M"}
a_to_m = crew.select(&first_half)

I passed the lesson but I seem to be getting this result
wrong number of arguments (0 for 1)

Any errors?


I tried you code in a windows 8.1 IE11 environment
and got a pass....
Maybe a reset Browser will help....
