There is currently nothing in your code which would surround the value with double quotes; you destructure the value and then just assign it to the double-quoted key in your accumulator object. Also I assume this is a typo? accum["${key}"] Template literal strings require backticks. If you're trying to replicate JSON.stringify you're going to have to get a good understanding of how different types of value get serialised, and think about how you can differentiate them in your code.

I know this is simple with `JSON.parse()` but that will not seem to work in my case. I think the issue is that `JSON.parse()` works only when the object is in the format of `{"key": "value"}` not in a `{key: "value"}` like I have. Below is a copy of the string that needs to be converted to JSON along with the error message.
