615 Points'for' loops
Basically, I want to do the following # Add number to destination if number # is less than 4
This code works:
def array_copy(source)
destination = []
for i in source
destination.push(i) if i < 4
end
return destination
end
BUT this code does NOT
def array_copy(source)
destination = []
for i in source
if i < 4
destination.push(i)
end
return destination
end
Why do I need to specify the method first eg. destination.push(i) if i < 4
instead of using a conditional first
eg. if i < 4 destination.push(i)
? They look like they should do the same thing to me. Maybe I'm missing a key part of this code "pattern".

Treehouse Guest TeacherHi Lucas Ackerknecht in your second code snipped your are missing an "end" before the "return" line which is what is causing the problem.
