3,031 PointsReturn vs. Puts
I noticed in one of my challenges it asked me to "return" a specific string. Well I used the term "puts" and kept getting it wrong. I changed puts to return and it was correct.
My question is what is the big difference between the 2?

Treehouse TeacherThe difference is one outputs the value to the screen. The other sends back or returns the value to the code that called it. Using return is a way to pass information around in your program while the puts is simply for outputting the information. Hope this helps!

In Ruby, every method returns the evaluated result of the last line that is executed.
It is very different from the Javascript world
However, a important feature of return is that it exits from your function (prematurely)
Hope this helps! Cheers,
