js数组去重

数组去重：1.

var aa=[1,3,5,4,3,3,1,4]
function arr(arr) {
var result=[]
for(var i=0; i<arr.length; i++){
if(result.indexOf(arr[i])==-1){
result.push(arr[i])
}
}
console.log(result)
} 
arr(aa)

2.

let array = Array.from(new Set([1, 1, 1, 2, 3, 2, 4]));
console.log(array);
// => [1, 2, 3, 4]

冒泡排序：

var array = [5, 4, 3, 2, 1];
var temp = 0;
for (var i = 0; i < array.length; i++)
{
for (var j = 0; j < array.length - i; j++)
{
if (array[j] > array[j + 1])
{
temp = array[j + 1];
array[j + 1] = array[j];
array[j] = temp;
}
}
}
console.log(array);
