找出数组中出现次数最多的数

function aa(arr){

var tempele;

var tempcount=1;

for(var i=0,len=arr.length;i

var count=1;

for(var j=i+1,len=arr.length;j

if(arr[i]==arr[j]){

count++;

arr.splice(j,1);

j--;

}

if(count>tempcount){

tempcount=count;

tempele=arr[i];

}

}

count=1;

}

return tempele;

}

console.log(aa([1,3,4,4,3,5,6,6,7,8,6]));
