--- js> Object.getOwnPropertyNames(new Proxy({}, {ownKeys: () => [0]})) ["0"] js> Object.getOwnPropertyNames(new Proxy({}, {ownKeys: () => [{toString: () => { print("toString called"); return "" }}]})) toString called [""] --- Expected: Both calls to Object.getOwnPropertyNames() throw a TypeError Actual: Non-String/Symbol values are converted to strings
Going to fix this by re-implementing this method. Thanks.
