How to compare a fixed date stored in an object with the current date in JavaScript?

Below is the fixed date stored in an object, write a function that compares a date with the current date:

const docData = {
  DateTransport: "2022-01-01",
  TypeHeureDepart: "02:15",
};

I wrote the below solution but I think there may be a time zone problem?

const docData = {
  DateTransport: "2022-01-01",
  TypeHeureDepart: "02:15",
};
// true: past ; false: now or future
const docDataDate = new Date(2022, 0, 1, 2, 15, 0, 0);
const currentDate = new Date();

function checkTime() {
  if (docDataDate >= currentDate) return false;
  return true;
}
console.log(checkTime());

Above solution has some issues below:

a. I shouldn't assign variables outside of the function
b. I didn't use docData
c. The function is not reusable
d. there's no input in this function

// true: past ; false: now or future

const docData = {
  DateTransport: "2022-01-01",
  TypeHeureDepart: "02:15",
};

function checkTime(docData) {
  const { DateTransport, TypeHeureDepart } = docData;
  const docDataDate = new Date(
    `${DateTransport} ${TypeHeureDepart || "00:00"}`
  );

  return new Date() > docDataDate;
}
console.log(checkTime(docData));

There are some important details:

1. When compared with two date, it needs to be same format
   1.1 if I use concat to connect the strings, it needs to be:

new Date(docData["DateTransport"] +'T'+docData["TypeHeureDepart"]+':00')
or
new Date(docData.DateTransport + "T" + docData.TypeHeureDepart + ":00")

1.2 use template literals: attention to the space or add a "T" in between them

const docDataDate = new Date(
  `${DateTransport} ${TypeHeureDepart || "00:00"}`
);
