Sometimes things click. Sometimes they don’t.
When I started going through my first Ruby lessons, there were one thing I didn’t understand that tripped up many of my labs.
Return
The lab instructions say to “return true or false,” so my code should look like this, right?
def my_method(arg)
if my_array.include?(arg)
return true
else
return false
But the instructions say “return,” I’m so confused!
If I don’t use return how do I return something? By writing nothing.
What?!? Replace return in your code with nothing.
def my_method(arg)
if my_array.include?(arg)
true
else
false
Implicit returns! Simple enough to be confusing.
