Synonyms

February 25, 2006 at 5:37 pm · Filed under All, Higher Order Procedures, Ruby

Time to play with synonyms. Let me know which versions you like better.

result = 0
0.upto(arr.length) do |i|
  result += arr[i]
end

or

arr.inject{|x,y| x + y}

How about this one?

0.upto(arr.length) do |i|
  arr[i] = 10+arr[i]
end

or

arr.map! {|x| 10 + x}

Higher-order procedures are h0t!

    The last one. Short and sweet. Good job.

    Have you redefined collect in your install, was that an intended inject call, or something entirely different?

    Good call, Mike. I must have been playing fast and loose w/ my keyboard. It’s now fixed to be an inject.
