I'm trying to convert string to object with the below code:

wishlisted= [ '626601b89f1c16d0e42fd58e' ]
console.log(wishlisted.map(id => ({ id })));

Output for this came as:

[ { id: '626601b89f1c16d0e42fd58e' } ]

But from the output, I think id is of String type. I want to return it just like MongoDB's id, like: 626601b89f1c16d0e42fd58e, not as a string.

When I tried to check the type of id using:

console.log(typeof wishlisted[0].id);

it came as undefined. What could be the best way to do this type casting?
