Tell us what’s happening:
Hi everybody! Just got a very quick and basic question:
Inside my function at the bottom, why does it have to be
return contacts[i][prop]
and why does this not work?
return contacts[i].prop
Any help greatly appreciated!!
Your code so far
//Setup
var 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(firstName, prop){
// Only change code below this line
for(var i = 0; i < contacts.length; i++){
if(firstName === contacts[i].firstName){
if(contacts[i].hasOwnProperty(prop)){
return contacts[i][prop];
} else {
return "No such property";
}
}
}
return "No such contact";
// Only change code above this line
}
// Change these values to test your function
lookUpProfile("Akira", "likes");
