What just happened?

Here is the output to Unity's Console.

The analysis of code is as follows:

• The code on line 8 is as follows:

  Dictionary<int, string> myFavoritePonies = new Dictionary<int, string>();

  Declaring a Dictionary is very similar to declaring a List.

  A Dictionary requires you to specify the type for the Key.

  This example used integers for the keys.

• The code on lines 10 and 11 is as follows:

  myFavoritePonies.Add(10, "Princess Cadence");
  myFavoritePonies.Add(20, "Fluttershy");

  Here you added two ponies using Add, just like you did for a List.

• The code on lines 12 and 18 with its description is as follows:

  myFavoritePonies[30] = "Nightmare Moon";
  myFavoritePonies[40] = "Rainbow Dash";

  Here you added ponies by assigning the pony name to a particular dictionary key.
