"this" inside prototype method

[lasjorg]

Issue description or question

this contains the prototype function.

Sample code

Array.prototype.logOnly = function (callback) {
  console.log(this); // [ true, false,  logOnly: λ ]
};

[true, false].logOnly(Boolean);

But not if this is empty.

Array.prototype.logOnly = function (callback) {
  console.log(this); // []
};

[].logOnly(Boolean);

Quokka.js Console Output

[ true, false,  logOnly: λ ]

Tested with ​Quokka v1.0.643 using Node 18 and 20.

I would assume this isn't intended or expected behavior?

Thanks for reporting the error.

Inline values for logged Arrays no longer display any properties that may exist on the array itself, you will now only see the Array values. You can still see and explore other properties that may exist on the array using Value Explorer.

Please update to Quokka for VS Code v1.0.644, it will fix the problem.
