Why is using "Return "safe"" right when "Puts "safe"" wrong?
So far in the lessons, we have been instructed to use "puts", and I learned in the community that "return" is the right. I found this also in the community: https://teamtreehouse.com/community/what-is-the-difference-between-puts-vs-return-when-defining-a-method
My big point (&&) question, did I miss something in the instruction up-to-this point because we never talked about "return".
Why is this the right answer:
def check_speed(car_speed) # write your code here if (car_speed >= 40) && (car_speed <= 50) return "safe" else return "unsafe" end end
when this is this is the wrong answer"
def check_speed(car_speed) # write your code here if (car_speed >= 40) && (car_speed <= 50) puts "safe" else puts "unsafe" end end

Hiya there! "return" is the right way coz the challenge asked you to return the variable , not output to the console. Also one more thing i'd like to mention here is that you dont even need to use return keywords in your loops or function. Why? 'coz Ruby does an implicit return and assumes the last statement is returning something. So finally your code should look like this:
def check_speed(car_speed) if (car_speed >= 40) && (car_speed <= 50) "safe" else "unsafe" end end
