根据属性值对对象数组进行排序

Question

假设我有一个这样的对象数组：

let array = [
{Course: “A”, Week: “3”}, 
{Course: “B”, Week: “5”},
{Course: “”, Week: “”}, 
{Course: “”, Week: “”},
{Course: “”, Week: “”}, 
]

如何修改此数组，以便根据 Week 的值将对象放置在数组中？例如，一周中值为 3 的对象将是数组中的第三个元素（索引 2）吗？换句话说，与该索引上的元素交换位置？

Answer 1

let array = [{Course: “A”, Week: “3”}, 
{Course: “B”, Week: “5”},
{Course: “”, Week: “”}, 
{Course: “”, Week: “”},
{Course: “”, Week: “”}]   

const list = array.sort((a,b) => a.Week - b.Week);
