I need to check whether the status is approved or not, so i check it if it is empty. Whats the most efficient way to do this?

RESPONSE

 {
      "id": 2,
      "email": "[email protected]",
      "approved": {
        "approved_at": "2020"
      },

    const checkIfEmpty = (user) => {
    if (Object.entries(user.verified).length === 0) {

You can do this way

const checkIfVerifiedExists = (user) => {
    if (user && user.verified && Object.keys(user.verified).length) {
        return true;
    }
    return false;
};

console.log(checkIfVerifiedExists(null));
console.log(checkIfVerifiedExists({something: "a"}));
console.log(checkIfVerifiedExists({verified: null}));
console.log(checkIfVerifiedExists({verified: ""}));
console.log(checkIfVerifiedExists({verified: "a"}));
console.log(checkIfVerifiedExists({verified: "a", something: "b"}));

Or More simple You can use Ternary Operator

const checkIfVerifiedExists = (user) => {
    return (user && user.verified && Object.keys(user.verified).length) ? true : false
};

console.log(checkIfVerifiedExists(null));
console.log(checkIfVerifiedExists({something: "a"}));
console.log(checkIfVerifiedExists({verified: null}));
console.log(checkIfVerifiedExists({verified: ""}));
console.log(checkIfVerifiedExists({verified: "a"}));
console.log(checkIfVerifiedExists({verified: "a", something: "b"}));
