You did not include an answer to “Tell us what’s happening”. What have you tried? What isn’t working as expected? What tests are failing? What don’t you understand? What do you understand?

well see i continue to try and find out what is wrong with this

 function whatIsInAName(collection, source) {
  // "What's in a name? that which we call a rose
  // By any other name would smell as sweet.”
  // -- by William Shakespeare, Romeo and Juliet
  var srcKeys = Object.keys(source);

  // filter the collection
  return collection.filter(function (obj) {
    return srcKeys
      .map(function(key) {
        return obj.hasOwnProperty(key) && obj[key] === source[key];
      })
      .reduce(function(a, b) {
        return a && b;
      });
  });
}

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

But i just can’t find it

You question was related to Pairwise challenge, but you posted code for Wherefore Art Thou. Just replace the code you pasted above with the correct code you want us to review.
