数组删除重复数据排序转换字符串

var arr = [1,7,0,3,2,3,54,4,4,51,45,53,4,3];
console.log('arr',arr);
var array = arr.sort(mySort); //按规则排序
console.log('array',array);
var newArr = [];
for (var i = 0; i < array.length; i++) { //删除重复数据
    if (newArr.indexOf(array[i]) == -1) {
        newArr.push(array[i]);
        }
}
console.log('newArr',newArr);
        
// 排序规则
function mySort(a,b) {
    return a - b;
}
