Build a Cargo Manifest Validator - Build a Cargo Manifest Validator

JavaScript

Tell us what’s happening:

I am working on ‘Build a Cargo Manifest Validator’ challenge included in the ‘JavaScript Certification’ course. My code passes all the tests except for the one at # 14: “If the input manifest object is not valid, your validateManifest function should return an object describing missing and/or invalid properties.”

I have tried all that I could think of but cannot seem to go past this test. When searching on the forums, I noticed a recent similar post but still need help / hint. Please help.

Your code so far

function normalizeUnits(manifest) {
  const m1 = {};

  m1.containerId = manifest.containerId;
  m1.destination = manifest.destination;

  if (manifest.unit == 'lb'){
    m1.weight = manifest.weight * 0.45;
    m1.unit = 'kg';
  }else {
    m1.weight = manifest.weight;
    m1.unit = manifest.unit;
  }
  
  m1.hazmat = manifest.hazmat;
  
  return m1;
}



function validateManifest(manifest){
  const m1 = {};

if ((typeof(manifest.containerId) != 'number') && (!(manifest.containerId)) ||(manifest.containerId === 'undefined') ){
    m1.containerId = "Missing";
  } else if (!(Number.isInteger(manifest.containerId)) || manifest.containerId <= 0) {
    m1.containerId = "Invalid";
  }

  if (!(manifest.destination)){
    m1.destination = "Missing";
  } else if (!(typeof(manifest.destination) == 'string') || (manifest.destination.trim() == "")) {
    m1.destination = "Invalid";
  }

  if (!(manifest.weight) && (!Number.isNaN(manifest.weight))){
    m1.weight = "Missing";
  } else if (!(typeof(manifest.weight) == 'number') || Number.isNaN(manifest.weight) || manifest.weight <= 0) {
    m1.weight = "Invalid";
  }

  if (!(manifest.unit)){
    m1.unit = "Missing";
  } else if (!(manifest.unit == 'lb' || manifest.unit == 'kg')) {
    m1.unit = "Invalid";
  }

  if (typeof(manifest.hazmat) == 'undefined'){
    m1.hazmat = "Missing";
  } else if (!(typeof(manifest.hazmat) == 'boolean')) {
    m1.hazmat = "Invalid";
  }

  return m1;
}



function processManifest(manifest) {

  if (Object.keys(validateManifest(manifest)).length == 0) {
    console.log("Validation success: " + manifest.containerId);
    console.log(`Total weight: ${normalizeUnits(manifest).weight} kg`);
  } else {
    console.log(`Validation error: ${manifest.containerId}`);
    console.log(validateManifest(manifest));
  }

}

Welcome back @pramod.lumb ,

Failing Test #14 points to an issue in your validateManifest function. Please go through the user stories again carefully to make sure you are meeting the requirements.

What if manifest.destination is an empty string? Does that mean the property is missing or does that mean the property’s value is invalid?

Happy coding!

Thanks a ton, @dhess .

I have been able to successfully complete this challenge by re-looking at the validation checks included in my code and ensuring completeness as per the requirements.

Thanks,

Pramod
