js 数组排序

// 方法1.sort()

let array = [1,5,9,23,45,13,98,113,90];

function reorder1() {

return array.sort((a,b)=>a-b);

}

console.log(reorder1());

 

 

// 方法2 冒泡排序

function reorder2() {

let len = array.length;

for(let i = 0; i<len;i++) {

for(let j = 0; j < len-i; j++) {

if(array[j+1] > array[j]) {

let temp = array[j];

array[j] = array[j+1];

array[j+1] = temp;

}

}

}

return array.reverse();

}

console.log(reorder2());
