Tell us what’s happening:

Code works, the Chckmark does not. Please help so I could complete this lab :).

Your code so far

Consider this object

   { containerId: -6,
     destination: 123,
     weight: 0,
     unit: 'pounds',
     hazmat: true }

what should validateManifest return?

is the weight valid?

what about this object?

 destination: ' ', weight: NaN, unit: 'kg', hazmat: 1 }

is the hazmat valid?

I fixed up the issues you pointed out, but I still can’t finish the lab..

Is the linebreak \n something you are asked to add?
