{name: 'Poppy', breed: 'Pug', owner: 'Anat'} ];

function getPugOwners(dogs) { 
  return dogs.filter(dog => dog.breed=='Pug').map(dog => dog.owner);
}

I wish did fix the issue. I have an IEnumerable list of date/value pairs that I am returning as a Json list to flot. However, when I call JsonResult(), the result looks like this: , It sounds like you just need to return a string like this:
code :
var builder = new StringBuilder();
builder.Append("[");
foreach (var item in listOfDateTimes)
    builder.AppendFormat("[{0}, {1}], ", item.Key, item.Value);
var result = builder.ToString().TrimEnd(new char[]{',',' '}) + "]";
return result;

With these it helps I'm having a terrible time trying to pull out some values out of an array. Here is a slimmed down version of the array. , Edit:
code :
foreach( $properties as $v ) {
 foreach( $v as $k => $m ) {     

  if( strpos($k, 'MEDIA_IMAGE_TEXT_') !== FALSE  ) {        
    $new_array[] = array('PropertyID' => $v['PropertyID'], 'IMAGE'=>$prev, 'IMAGE_TEXT'=>$m );
  } 

  if( strpos($k, 'MEDIA_IMAGE_') !== FALSE ) {
    $prev = $m;  //var_dump($prev);
  }

 }
}

Search an Array containing strings of names, return names with length of X

around this issue Seems like you do not search names with a length of 2, but being composed of 2 names.
Select by the number of name parts:
code :
["Jim Bob", "Jim", "Billy Bob"].select { |names| names.split.length == 2 }
#=> ["Jim Bob", "Billy Bob"]
["Jim Bob", "Jim", "Billy Bob"].select { |name| name.count(' ') == 1 }
#=> ["Jim Bob", "Billy Bob"]

d = dict(A=12.74087388,       
B=12.48817861,
C=12.31249807,
D=12.95688859,
E=12.49693343,
F=11.51090636,
G=10.16505019,
H=11.99872655)
>>> sorted(d, key=d.get)
['G', 'F', 'H', 'C', 'B', 'E', 'A', 'D']
from operator import itemgetter
print(sorted(d.items(), key=itemgetter(1)))
[('G', 10.16505019),
 ('F', 11.51090636),
 ('H', 11.99872655),
 ('C', 12.31249807),
