client.user.presence returns a Presence, a very complex object. I believe you are looking for Presence#status, which will return online, offline, idle, or dnd
userinfo.presen = message.client.user.presence.status;
Also, instead of adding every property to the userinfo object after it’s been defined, you could condense your code using object destructuring:
// change:
let userinfo = {};
userinfo.bot = message.client.user.bot;
userinfo.createdat = message.client.user.createdAt;
userinfo.discrim = message.client.user.discriminator;
userinfo.id = message.client.user.id;
userinfo.mfa = message.client.user.mfaEnabled;
userinfo.pre = message.client.user.premium;
userinfo.presen = message.client.user.presence.status;
userinfo.tag = message.client.user.tag;
userinfo.uname = message.client.user.username;
userinfo.verified = message.client.user.verified;
userinfo.avatar = message.client.user.avatarURL;
// to:
const {
bot,
createdAt,
discriminator,
id,
mfaEnabled, // if you want to create an alias, you could write `mfaEnabled: alias`
premium,
presence: { status },
tag,
username,
verified,
avatarURL,
} = message.client.user;
console.log(username) // same as `message.client.user.username`, but way shorter!
