数组去重问题

function uniq(array){
    var temp = {}, r = [], len = array.length, val, type;
    for (var i = 0; i < len; i++) {
        val = array[i];
        type = typeof val;
        console.log(‘temp[val]=‘+temp[val]);
        console.log(‘temp=‘+temp);
        if (!temp[val]) {
            temp[val] = [type];
            console.log(temp[val]);
            r.push(val);
        } else if (temp[val].indexOf(type) < 0) {
          console.log(temp[val]);
            temp[val].push(type);
            r.push(val);
        }
    }
    return r;
}

var aa = [1,2,"2",4,9,"a","a",2,3,5,6,5];
console.log(uniq(aa));
