Всем доброго дня!
Подскажите, пожалуйста, никаких образом не хочет выполняться 15-й пункт. Через ИИ прогонял, сам голову ломаю и не могу понять в чем проблема. При вводе данных выдает необходимые параметры, а по факту тест не пропускает 15-й пункт как выполненный.
Если входной объект манифеста недействителен, ваша validateManifestфункция должна вернуть объект, описывающий отсутствующие и/или недействительные свойства.
Your code so far
function normalizeUnits(manifest) {
const newManifest = { ...manifest };
if (newManifest.unit === "lb") {
newManifest.weight = newManifest.weight * 0.45;
newManifest.unit = "kg";
}
return newManifest;
}
function validateManifest(manifest) {
// 1. Если передан не объект — всё Missing
if (typeof manifest !== 'object' || manifest === null) {
return {
containerId: "Missing",
destination: "Missing",
weight: "Missing",
unit: "Missing",
hazmat: "Missing"
};
}
const errors = {};
// Безопасная проверка собственного свойства (работает даже с Object.create(null))
const hasOwn = Object.prototype.hasOwnProperty.call.bind(Object.prototype.hasOwnProperty);
// containerId
if (!hasOwn(manifest, 'containerId')) {
errors.containerId = "Missing";
} else {
const v = manifest.containerId;
if (typeof v !== 'number' || !Number.isInteger(v) || v <= 0) {
errors.containerId = "Invalid";
}
}
// destination
if (!hasOwn(manifest, 'destination')) {
errors.destination = "Missing";
} else {
const v = manifest.destination;
if (typeof v !== 'string') {
errors.destination = "Invalid";
} else if (v.trim() === '') {
errors.destination = "Invalid";
}
}
// weight
if (!hasOwn(manifest, 'weight')) {
errors.weight = "Missing";
} else {
const v = manifest.weight;
if (typeof v !== 'number' || Number.isNaN(v) || v <= 0) {
errors.weight = "Invalid";
}
}
// unit
if (!hasOwn(manifest, 'unit')) {
errors.unit = "Missing";
} else {
const v = manifest.unit;
if (typeof v !== 'string') {
errors.unit = "Invalid";
} else {
const lowered = v.trim().toLowerCase();
if (lowered !== 'kg' && lowered !== 'lb') {
errors.unit = "Invalid";
}
}
}
// hazmat
if (!hasOwn(manifest, 'hazmat')) {
errors.hazmat = "Missing";
} else {
const v = manifest.hazmat;
if (typeof v !== 'boolean') {
errors.hazmat = "Invalid";
}
}
return errors;
}
function processManifest(manifest) {
const errors = validateManifest(manifest);
if (Object.keys(errors).length === 0) {
console.log(`Validation success: ${manifest.containerId}`);
const normalized = normalizeUnits(manifest);
console.log(`Total weight: ${normalized.weight} kg`);
} else {
console.log(`Validation error: ${manifest.containerId}`);
console.log(errors);
}
}

If you have a question about a specific challenge as it relates to your written code for that challenge and need some help, click the Help button located on the challenge.
The Help button will create a new topic with all code you have written and include a link to the challenge also. You will still be able to ask any questions in the post before submitting it to the forum.
I’ve edited your post to correctly format the code. In the future, please use this reference for that:
There are two ways you can format your code to make it easier to read and test:
After you copy/paste your code into the editor, select it by dragging your cursor over it then click the (</>) button in the toolbar to automatically wrap your code in backticks. (You can click on the animated demo image below to enlarge it.)
Manually add three backticks on a new line above your code and on a new line after your code. Note that a backtick is NOT the same as a single quote('). To find the backtick key on your keyboard, see this post.
To see changes to your post as you make them, you can click the (M+) button on the toolbar to bring up the rich text editor:
В данном примере предложена версия программы в не самом оптимальном варианте, поскольку в неоднократных попытках реализации 15-го пункта и учета возможных исходов поведения программы - успешных результатов, увы, не достигнуто.
