Is there a difference between
def get_name name = "" loop do
and
def get_name() loop do
I'm thinking there might be a subtle difference but maybe not? :)
Thank you, Ingrid

Yeah, the variable would not be accessible by anything outside of the loop, so you would not be able to return the variable. It would be a "local variable".
I'm sorry, didn't read through the article enough... Not entirely sure when they bring up inte course, but I'm sure they will at some point.
No problem, only happy to help!
Keep on coding, nothing fun in life is easy! ;)

21,385 PointsYes, it would.
It all comes down to the scoop of the variable "name". If you do not declare it outside of the loop it would only be accessible inside of the loop and therefore you wont be able to return it outside of the loop. But, if you declare it outside of the loop but inside of the function it will be accessible in the whole function. (Like you do with the empty string)
Take a look at this link if you donΒ΄t understand: http://www.techotopia.com/index.php/Ruby_Variable_Scope.
And sorry if i misspelled or if my grammar is off-point. Not a native english speaker... ;)
Best regards Jacob Jonsson

10,616 PointsHey you're English is not a problem!!! Ok i understand what you are saying..also ...would it be correct of me to say that if the empty string wasn't declared outside of the loop it wouldn't be accessible by other methods if it were needed?
I was reading the article you included and wow...I'm not there yet ...but I'm working on it! :) Also, at some point will Treehouse insist on the syntax...I would imagine in the real world developers us it....maybe...maybe not?
Once again thanx for your help Jacob!!

10,616 PointsHi Jacob, my question is...would it make a difference if in the code below i left out the empty string variable name?
