the case statement returns whatever the result of whatever meets the condition so no need to use the grade variable anywhere within this function.
see: https://ruby-doc.org/docs/keywords/1.9/Object.html#method-i-case
| grade = 'F' | ||
| end | ||
|
|
||
| return grade |

ruby functions will return the last evaluated expression so explicit returns aren't used often except in the case of guard clauses.
example where someone might use an explicit return.
def is_tall?(person)
return false if person.short?
true
end

| sorted_array = array.sort_by { |word| word.length } |

this can also be written a bit more tersely but still readable. see: https://ruby-doc.org/core-2.5.1/Enumerable.html#method-i-min_by
