This somehow works for the first two cases, but it’s not working for the last 2 cases.

function arrContainsObj(arr, obj){
  for (var i=0; i < arr.length; i++){
    if(arr[i] == obj){
      return true;
    }
  }
  return false;
}




function whatIsInAName(collection, source) {
  // What's in a name?
  var arr = [];
  // Only change code below this line
  
  collection.forEach(function(val){
    var keys = Object.keys(source);
    for (var i=0; i < keys.length; i++){
      if (val.hasOwnProperty(keys[i]) && val[keys[i]] == source[keys[i]]){
        if (!arrContainsObj(arr, val)){
          arr.push(val);
        }
        
      }
    }
  });
  
  // Only change code above this line
  return arr;
}

whatIsInAName([{ "a": 1, "b": 2 }, { "a": 1 }, { "a": 1, "b": 2, "c": 2 }], { "a": 1, "b": 2 , "c" : 2});
