javascript - Access array element with a dot in its name -

i'm reading data database , loading in array. when print console this:

 [  {'person.name':'name1', total:1},  {'person.name':'name2', total:100}  ]

so iterate through code:

for(var i=0;i<arr.length;i++){     console.log(arr[i].total); }

i can access total how can access 'person.name'?

access array :

arr[i]['person.name'];
