Ok I'm dumb, I exited my for loop too early:
function lookUp( firstName, prop ){
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";
}
This works.

I think you are confused about what return does. Your code will only do one iteration and return "No such contact". Return immediately stops the function to execute. Here is a fiddle of what I mean demonstrated with console.log https://jsfiddle.net/oegw3a4y/
In your situation, the first iteration evaluates to false in the first if statement and immediately goes to the else.

var result;
for(var i = 0;i<contacts.length;i++)
{
if((contacts[i].firstName===firstName) && (contacts[i].hasOwnProperty(prop)))

}
else if (contacts[i].firstName!==firstName) {

}
else if (contacts[i].hasOwnProperty(prop) !== true) {
result = "No such property";
}
}
return result;
}

Here's what I had, its basically a variation of what Minimanimalist did but without the flag. Mine works on the assumption that if the contact exists and it has the property we are looking for it will be returned before it gets to the "No such contact". Please excuse formatting.
function lookUp(firstName, prop){// Only change code below this linefor(var i=0;i<contacts.length;i++){ if(contacts[i].firstName === firstName){ if(contacts[i].hasOwnProperty(prop)){ return contacts[i][prop];} else { return "No such property";} }}return "No such contact"; 2 of 3

Looks like you're returning too quickly. You want to be able to check all the contacts first.
