Wherefore art thou - sloppy code works, but how could I make it better?

So I solved the challenge with the code below, but I know it would cause some complications if the source object ever had more than two keys. What are some ways I could simplify this to make it shorter and more efficient?

**My code so far: **


function whatIsInAName(collection, source) {
  // new array that will be pushed to
  let arr = [];

  // array of the keys in the source object
  let sourceKeys = Object.keys(source);

  // array of the values in the source object
  let sourceValues = Object.values(source);

  console.log(sourceKeys);
  console.log(sourceValues);

  // looping through the collection array
  for (let i = 0; i < collection.length; i++) {
    // if there are multiple keys in the source object, we will have to check for sourceKeys[0], sourceKeys[1],
    // sourceValues[0], and sourceValues[1]
    if (sourceKeys.length > 1) {
      // if the object has BOTH keys in the source object
      if (collection[i].hasOwnProperty(sourceKeys[0]) && collection[i].hasOwnProperty(sourceKeys[1])) {
        // and if the values in the source object exist in the object
        if (Object.values(collection[i]).indexOf(sourceValues[0]) >= 0) {
          if (Object.values(collection[i]).indexOf(sourceValues[1]) >= 0) {
            arr.push(collection[i]);
          }

        }
      }
      // if there is only one key in the source object, we only have to account for the [0] index
    } else if (sourceKeys.length === 1) {
      // if the object has the key in the source object
      if (collection[i].hasOwnProperty(sourceKeys[0])) {
        // if the value in the source object exists in the object
        if (Object.values(collection[i]).indexOf(sourceValues[0]) >= 0) {
          arr.push(collection[i]);
        }
      }
    }

  }

  // Only change code above this line
  return arr;
}

whatIsInAName([{ "apple": 1, "bat": 2 }, { "bat": 2 }, { "apple": 1, "bat": 2, "cookie": 2 }], { "apple": 1, "bat": 2 });
