Hi @JSerZANP , I have an idea on resolving this issue:
Transform below codes

const blog = "https://jser.dev"
/*                    ^
       [JSer.dev is the *homepage* for JSer.]
       [Check it out! [jser.dev](https://jser.dev)]
*/
// This is a normal comment

into

const blog = "https://jser.dev"
//                    ^
//       [JSer.dev is the *homepage* for JSer.]
//       [Check it out! [jser.dev](https://jser.dev)]
// This is a normal comment

We can simply check the first content for each line, as I see another usage which looks like {/* [This is line 2] */} always has { as first content.
Once we have met /* we can add // before each content between /* and */, then remove */ to avoid unnecessary new line
