New learner here, I'm stuck on a practice question for a course and I'm not sure what it's asking me to do here. The problem is as follows:

Write a function that takes a user object, which represents a user of the Northcoders website, and returns the value of the password key from that object.

If the user object does not contain a password key, the function should instead return undefined.

A typical user object might look like this:

{ name: 'Lucy', password: 'n0rthc0derzzz' }

Requirements are as follows:

• Returns undefined when given a user object where no password key is present - check
• Returns a password from a user object when a password key is present - unchecked

Starting code is:

function retrievePassword (user) {
// Your code goes here...

So judging by //Your code goes here... I'm not supposed to change the arguments for the function since I'm supposed to write my code below.

Any help much appreciated! Thanks in advance!

I was stuck on this too for a while.

function retrievePassword (user) {
if (user.hasOwnProperty("password")){
  console.log(user.password);
  return user.password;
} else {
  return undefined;
}
}

CodePudding user response：

function retrievePassword (user) {
  return user.password
}

or

function retrievePassword ({ password }) {
  return password
}

or

const retrievePassword = ({ password }) => password

or

const retrievePassword = (user) => user.password

CodePudding user response：

var hh = ({ name : 'Lucy', password: 'n0rthc0derzzz' });

function retrievePassword(user) {

if (hh.hasOwnProperty(user)) { return (hh?.password) }

}

console.log(retrievePassword("name"))

Yeh, I steel stuck here but I can't find the way instead of "name" put "Lucy"
