Tell us what’s happening:

I’m having trouble passing instruction 14. Could anyone give me a hint? I’d really appreciate it :blush:
14. 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

let cargo1 = {
 containerId: 0,
  destination: 55,
  unit: "lb ",
  hazmat: "sc",
}

const normalizeUnits = (manifest) => {
  const newManifest = { ...manifest };

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

  return newManifest;
};

const validateManifest = (manifest) => {
  const errors = {};

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

  if (manifest.unit === undefined) {
    errors.unit = "Missing";
  } else if (
    typeof manifest.unit !== "string" ||
    !["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;
};

const processManifest = (manifest) => {
  const validationResult = validateManifest(manifest);

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



processManifest(cargo1)

**Okay, it worked. **

removed by moderator

I think it passed because function declarations are fully hoisted, while arrow functions assigned to const are not available before initialization.
