Why 'user' in serve side are in different format than say maybe browser side console.log result?

Question

in React/Nodejs App. I wish to get user.id value, but I cannot get it from frontend code, which after console.log, shows like so:

{token: 'eyJhbGciOiJIUzI1NiIsInR5cCI6IkpXVCJ9.eyJ1c2VybmFtZ…TMxfQ.ea2lwGVzuFebzHqWBFtCsJm-Sdt2YhuPMcclHW04tzg', username: 'root', name: 'Superuser'}

if I wish to get the value of user.id, then its undefined in my code.

On the server side, localhost:3000, user be shown like this:

{
username: "root",
name: "Superuser",
blogs: [
],
id: "6234ce14c654a312f8564fa3"
},

I am able to get user.id from server side user object with no problem.

Any idea why is it so? How can I get user.id in my frontend code. I wish to compare these two values, so give possiblity to the loggedin user to do deletion of user's data.
