Question

0.00/5 (No votes)

See more:

create an object employee with properties: --name as "rajesh" --phone as 9800000000, --symbol "email" as "rajesh@gmail.com". after creating the object, display: --all the keys of object "employee" --only private keys (symbols) --only public key (non symbol)

What I have tried:

let allkeys = {
return Object.allkeys(Employee)};

but it did not work in hacker rank

What did not work?

Member 14828342 11-May-20 6:33am

It is not accepting the return Object.allkeys(Employee) in hackerrank

Please edit your question, show the code that is not working and provide proper details of the problem, including any error messages.

I think my program is not clear
Can you provide me a snippet of code for the question ?
I clearly have no idea about the implementation, your code may help me to get the answer

That is like asking a doctor for the pills to make you better, when you have not explained what you are suffering from.

/*This is my code*/let email =Symbol();
let Employee = {
name : "rajesh",
phone :9800000000,
[email] : "rajesh@gmail.com"

};

let allKeys = {
keyss : Object.keys(Employee)
};
console.log(allKeys.keyss);
let privateKeys = {
p : Employee[email]
};
console.log(privateKeys.p);
let publicKeys = {
pu : Object.getOwnPropertyNames(Employee)
};
console.log(publicKeys.pu)

module.exports = {Employee, allKeys, privateKeys, publicKeys}

but still failed in hacker rank
can you find the mistake atleast now? and help with what went wrong
npm ERR! Test failed

Sorry, I don't know what "hacker rank" means or what the error is.

I have tried some of your code but the following statements do not work (allKeys remains undefined) so that is what you need to investigate:

let allKeys = {
keyss : Object.keys(Employee)
};
