javascript - 按升序对对象数组进行排序，但将所有零放在最后

Question

如果我有一个对象数组:

[{
    val: 0
}, {
    val: 1
}, {
    val: 0
}, {
    val: 3
}]

如何将其升序排序，但将零结尾保留，如下所示:

[{val:1}, {val:3}, {val: 0},{val: 0}]

如预期的那样，排序将零放在顶部。即使我添加逻辑以将零排序到最后:

array.sort((a,b) => {
    if (a.val === 0 || b.val === 0) return 1;
    return a.val < b.val;
});

Answer 1

如果a.val为0，则返回1。如果b.val为0，则返回-1

var array = [{val: 0}, {val: 1}, {val: 0}, {val: 3}];

array.sort((a, b) => {
  if (a.val === 0) return 1;        //Return 1 so that b goes first
  if (b.val === 0) return -1;       //Return -1 so that a goes first
  return a.val - b.val;
});

console.log(array);
