问题

我正在尝试从一个数组创建新的集合，但它返回一个空对象。我做错了什么？

const myArray = ["value1", "value2", "value3", "value1", "value2"];
const mySet = new Set(myArray);
Logger.log(mySet);

I am trying to create new Sets from an array but it is returning an empty object. What am I doing wrong?

const myArray = ["value1", "value2", "value3", "value1", "value2"];
const mySet = new Set(myArray);
Logger.log(mySet);

`new Set()` 返回 Set 对象。当您想查看该值时，可以尝试以下修改：

### 从：
	Logger.log(mySet);

### 到：
	Logger.log([...mySet]);

或

	Logger.log(Array.from(mySet));

`new Set()` returns the Set object. When you want to see the value, how about the following modification?

### From:
	Logger.log(mySet);

### To:

	Logger.log([...mySet]);

or

	Logger.log(Array.from(mySet));
