Hi everyone,
I want to loop through this array, but not for every index… only
indices that are
greater than 2.
@weights.each_index do |i|
end
Ted
@weights[2…-1].each_index{|i|
}
or
@weights.each_index{|i|
next if i<2
code
}
I think the first version makes a new object.

That would be
@weights[3…-1].each_index{|i|
}
(OP said “greater than 2”.)
But it does not work because each_index will start at 0. Rather you
probably meant
@weights[3…-1].each {|elem|
}
For the indexes only one can do
([email protected]).each {|i|
}
or
for i in [email protected]
end
Kind regards
robert
