💻 Code

console.log(new Set().add("hello!"));
console.log({
    s: new Set().add("hello!")
})

🙁 Actual behavior

Clicked "Run", then got this result:

[LOG]: Set (1) {"hello!"} 
[LOG]: {
  "s": {}
} 

🙂 Expected behavior

Should print out:

[LOG]: Set (1) {"hello!"} 
[LOG]: {s: Set(1)}

or maybe something like this:

[LOG]: Set (1) {"hello!"} 
[LOG]: {s: Set (1) {"hello!"}}

I wonder if this belongs in microsoft/TypeScript-Website instead of here? Although given microsoft/TypeScript-Website#2804 I'm not sure if it would be appropriate there either.

It definitely not for this issue tracker.

Since it's not critical, we wouldn't keep such an issue open, but a PR would be welcome.
