    this is the exact answer:

    def scoring(array)

    array.each do |user|

    user.update_score

    end

    • iterate through each of the element in array using each and call update_score on it

    end

    What is the significance of |user|?

      That binds each element of the list to the variable name user. Here is some equivalent code, in a less "Ruby" style.

      i = 0
while i < array.size
    user = array[i]
    # do stuff
    i += 1
end

    I did

    def scoring(array)
    array.each(&:update_score)
end

    def scoring(array)
  array.map(&:update_score)
end

    Can we see the source code for User? As well as how the array is defined/populated initially?

    Without it, it's just another blind "copy and paste, have blind faith that everything works as expected" problem.
