Answer 1

如果你想保留你的代码，你可以使用这个：

var months = ["April 2021","March 2021", "May 2021", "April 2020"];
let monthArray = ["January", "Febraury", "March", "April", "May", "June",
    "July", "August", "September", "October", "November", "December"];

months = months.sort((a,b)=>{
  const [monthA, yearA] = a.split(' '),
        [monthB, yearB] = b.split(' ');
  if (yearA === yearB)
    return monthArray.indexOf(monthA) - monthArray.indexOf(monthB);
  return +yearA - +yearB
})

console.log(months)

使用排序（）和Date（）构造函数

js lang-js prettyprint-override">var months = ["April 2021", "March 2021", "May 2021", "April 2020"]

var sorted = months.sort((a, b) => new Date(a) - new Date(b))

console.log(sorted)
