JavaScript函数编写完成数组翻转

function sb(bn) {
let cv = [];
for (i = bn.length; i >= 0; i--) {
cv[cv.length] = bn[i];
}
return cv;
}
let a = sb([5, 6, 9, 8, 42, 236, 2]);
console.log(a);

使用函数进行冒泡排序

function a(b) {
for (let i = 0; i < b.length - 1; i++) {
for (let j = 0; j < b.length - i - 1; j++) {
if (b[j] > b[j + 1]) {
let temp;
temp = b[j];
b[j] = b[j + 1];
b[j + 1] =temp;
}
}
}
return b;
}
let c = a([5, 6, 9, 8, 2, 0, 3, 1]);
console.log(c);
