Tell us what’s happening:

I can not get my code to pass tests 21, 25 and 26. I feel like my outputs are correct so I would like some help please. Thank you

Your code so far

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

  if (copy.unit === "lb") {
    copy.weight = Math.round(copy.weight * 0.45 * 100) / 100;
    copy.unit = "kg";
  }

  return copy;
};

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

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

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

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

  if (!("unit" in manifest)) {
    errors.unit = "Missing";
  } else if (manifest.unit !== "kg" && manifest.unit !== "lb") {
    errors.unit = "Invalid";
  }

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

  return errors;
};

const 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 to the forum @rodrigocristo3,

Please declare your arrow functions with let instead of const since the tests are reassigning those functions.

Staff is working on getting a note up about this.

Happy coding

Great advice! I’ve been struggling with this issue for ages.
