`/Date(1646764200000+0530)/` is not a string, it's a RegExp ... did you mean `let dob = "/Date(1646764200000+0530)/"` — Bravo, Mar 12 '22 at 06:59
`new Intl.DateTimeFormat('en-GB').format(new Date(+(dob.replace(/^\/Date$(\d+)\+\d+$\/$/, '$1')))).replaceAll('/', '-')` — Bravo, Mar 12 '22 at 07:10

Converting to the DD-MM-YYYY requires formatting.

Here is one way to extract the date portion using the slice() method then formatting the output to your desired format. This assumes that the input date is always in the same form and length.

let dob = /Date(1646764200000+0530)/;

let date = new Date(+(""+dob).slice(6,19)).toLocaleString('en-GB',{year:"numeric",day:"2-digit",month:"2-digit"}).split("/").join("-");

console.log(date)
