Safe navigation operator
📝 Ruby
The safe navigation operator (&.) in Ruby allows you to call a method on an object that may be nil, returning nil instead of raising a NoMethodError.
Ruby
obj = nil
result = obj&.length
puts result # nil obj = "hello"
result = obj&.length
puts result # 5

yeah @brownk1991 i love &. but sometimes it masks a nil i wasn't expecting, making bugs harder to track down, specially in long chains.
