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.

So I'm going through freecodecamp and I'm solving the problems there, to keep in the loop with the programming and I've stumbled on a snag, and I'm not quite sure what's wrong. So I have an array of objects called contacts, and I need to create a function called lookUp(firstName, prop). More on stackoverflow.com

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.

Hi everyone, I'm new in programming, and I want to ask you if you could tell me why my code doesn't work? I have seen other solutions, and are ok for me, but this code that I made seems ok for me too, but I don't know why it doesn't work.
If I don't write the lasts “else if” and the “else return” the 3 first tests past, but when I try to accomplish the last “No such contact” and “No such property” instructions then the last 3 tests past but not the 3 first test. What am I missing? Thank you for your time.

I typed your code in, and it seemed to work for me! Maybe I’m missing something, but try hitting “reset this lesson.” Maybe something strange is occurring on your end.

Did you figure it out? Coincidentally, I'm having the same problem and my code looks very similar to yours. If I comment the 2 "else", the code passes the first 3 tests but not the other 3. If I de-comment them, the other 3 pass but not the first 3 even though the first part is supposed to run first. And it isn't just the tests. If I use console.log to check each test manually, the same happens ("Kristian", "lastName" console will change from "Vos" to "No such contact").
