here's have far js:

and json:

{"beers":[         {             "name":"surly wet",             "type":"ale"         },         {             "name":"spaten oktoberfest",             "type":"lager"         },         {             "name":"pliny elder",             "type":"ale"         },         {             "name":"summit ipa",             "type":"ale"         },         {             "name":"surly coffee bender",             "type":"porter"         },         {             "name":"lagunitas ipa",             "type":"ale"         } ]}
