How to show values of a Javascript Set() in Stackblitz console?
问题
I've been using stackblitz as a scratchpad for learning and testing javascript. I find it very convenient to use the real-time console updates while logging out lines of code.
One problem I've encountered is how the console outputs the results of a Set() method.
For example:
let numbers = [1, 1, 2, 2, 3, 3];
numbers = new Set(numbers);
console.log(numbers); // expect: Set(3) {1, 2, 3}
The output of console.log(numbers) in the Chrome inspector is Set(3) {1, 2, 3}. However, the output of the StackBlitz console is just Set {}.
I suppose this is just a quirk of the SB console, or is there a workaround that doesn't involve opening the Chrome inspector to view the contents of the Set()?

最糟糕的情况下，你可以简单地执行：
console.log([ ...numbers ]);
这将把 numbers 展开到一个数组中，然后打印出这个数组。
英文:
Worst case you can simply do:
console.log([ ...numbers ]);
This will spread numbers into an Array, and the Array will be logged.
