Console log WeakSet and WeakMap always empty #19001

  • Subsystem: powershell

Currently trying to console.log WeakSet or WeakMap will always display as empty.

var set = new WeakSet([{yes: true}]);
console.log(set); // logs WeakSet{}

var map = new WeakMap([[{yes: true}, true]]);
console.log(map); // logs WeakMap{}

I believe I understand why logging them does not work, but node should display a warning and/or should document this behavior.
