Tell us what’s happening:

  1. If the input manifest object is not valid, your validateManifest function should return an object describing missing and/or invalid properties.

Your code so far

function normalizeUnits(manifest) {
  const copy = { ...manifest };

  if ( copy.unit.toLowerCase() === "lb" ) {
    copy.weight = Number((copy.weight * 0.45).toFixed(2));
    copy.unit = "kg";
  }

  return copy;
}

function validateManifest(manifest) {

  if (
    manifest === null ||
    manifest === undefined ||
    typeof manifest !== "object" ||
    Array.isArray(manifest)
  ) {
    return {
      containerId: "Missing",
      destination: "Missing",
      weight: "Missing",
      unit: "Missing",
      hazmat: "Missing"
    };
  }
  let errors = {};

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

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

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

  if ( manifest.unit === undefined ) {
    errors.unit = "Missing";
  } else if (typeof manifest.unit != "string" || manifest.unit.toLowerCase().trim() == "" || !["kg", "lb"].includes(manifest.unit.toLowerCase()) ) {
    errors.unit = "Invalid";
  };

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

  return errors;
}

function processManifest(manifest) {
  const validateResult = validateManifest(manifest);

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


const testt = { containerId: 55, weight: 400, unit: "lb", hazmat: false }


processManifest(testt)

Welcome to the forum @fxrxlxx,

From the instructions:

  • weight: a positive number representing the cargo’s weight.

Your code:

Is zero a positive number?

Should you manipulate the value of unit before validating it?

Happy coding

thank you. it worked
