Does anyone see anything wrong with this code? Any help is appreciated!

function whatIsInAName(collection, source) {

  var srcKeys = Object.keys(source);

  return collection.filter(function) {
    for (var i = 0; i < srcKeys.length; i++) {
      if (
        !obj.hasOwnProperty(srcKeys[i]) ||
        obj[srcKeys[i]] !== source[srcKeys[i]]
      ) {
        return false;
      }
    }
    return true;
  });
}

whatIsInAName(
  [
    { first: "Romeo", last: "Montague" },
    { first: "Mercutio", last: null },
    { first: "Tybalt", last: "Capulet" }
  ],
  { last: "Capulet" }
);

What problems are you having? Can you narrow down what you think is wrong with it?

Everytime I try running the tests, it says “SyntaxError: unknown: Unexpected token”. Does that mean I wrote something wrong or does it mean something else?

“Unexpected token” almost always means that you have a mismatch of opening and closing symbols like braces ({}), parenthesis, (()), brackets ([]), etc. Check your braces and parentheses carefully and make sure that you have the right number of each and that the closing symbols are in the correct place.

The error message is pointing to this part here

once you clean that up then you should be getting a different error message concerning this part here

It doesn’t look like you defined obj anywhere.
