I do have one, but in spanish: Curso de JSON de Novato a Experto.

You can run those commands in a Browser Terminal (Developer Mode) or in a programm called Run JS

Hey Camilo, instead of using delete, you could set the pointer to null. #perfTip :p

On delete operation you can use got[character] = null; instead of delete got[character];. Take a look on jsperf.com/delete-vs-undefined-vs-...

Not works as CRU*D* operation, because the 'character' is not removed, just the values are replaced by null.

I tested changing on Delete script. When run the script show: Tyrion: null.

Can be used if you want leave the character, but remove his data.

Nice link BTW. I did not know about the performance comparison between null and delete
