my code fails the test and I do not see why ?
// Setup
const contacts = [
{
firstName: "Akira",
lastName: "Laine",
number: "0543236543",
likes: ["Pizza", "Coding", "Brownie Points"],
},
{
firstName: "Harry",
lastName: "Potter",
number: "0994372684",
likes: ["Hogwarts", "Magic", "Hagrid"],
},
{
firstName: "Sherlock",
lastName: "Holmes",
number: "0487345643",
likes: ["Intriguing Cases", "Violin"],
},
{
firstName: "Kristian",
lastName: "Vos",
number: "unknown",
likes: ["JavaScript", "Gaming", "Foxes"],
},
];
function lookUpProfile(name, prop) {
// Only change code below this line
for (let i = 0; i <= contacts.length -1; i++){
if (contacts[i].firstName === name && contacts[i].hasOwnProperty(prop)) {
return contacts[i][prop];
} else {
return "No such property";
}
return "No such contact";
}
// Only change code above this line
}
lookUpProfile("Akira", "likes");

Link to the challenge:
Which test does it fail?
When can you conclude that no contacts match?
for example these two tests :
lookUpProfile("Kristian", "lastName") should return the string Vos
lookUpProfile("Sherlock", "likes") should return ["Intriguing Cases", "Violin"]
So… when can you say that no contacts match?
if there are no matches from the for loop.
I changed that already but still those tests fail
new code :
function lookUpProfile(name, prop) {
// Only change code below this line
for (let i = 0; i <= contacts.length -1; i++){
if (contacts[i].firstName === name && contacts[i].hasOwnProperty(prop)) {
return contacts[i][prop];
} else {
return "No such property";
}
}
return "No such contact";
// Only change code above this line
}
Now lets look at this part
When will this be true? When will this be false?
it will be true if the given name is equal to the firstname of a person and if that person has that property.
And under what conditions will it be false?..
if a person has not that name or if that person has not that property.
So it looks i cannot use a &&
here
There are lots of ways to fix it, but you’ve got the core of the issue.
