Nils and method chaining

Question

I\'m just breaking into the ruby world and I could use a helping hand.

Suppose b is nil.

I\'d like the following code to return n

Answer 1

"try" is very clean, as lucapette said. More generally, you could also use a begin-rescue-end block too, depending on your situation.

begin
  a.b.c("d").e
rescue NoMethodError=>e
  return nil
end
