    You could just compare only the year, month, and day.

    let d = new Date("2023-07-15"), now = new Date();
let matches = d.getYear() === now.getYear() 
            && d.getMonth() === now.getMonth()
            && d.getDate() == now.getDate();
console.log(matches);

    To compare the date returned from the API with the current date both dates must have the same format.

    here is an example of code that does this:

    // Get the current date
let currentDate = new Date().toISOString().split('T')[0];

// Convert the API date 
let apiDate = new Date("2023-07-14").toISOString().split('T')[0];

// Compare the two dates
if (apiDate === currentDate) {
  console.log("The API date is equal to the current date.");
} else if (apiDate < currentDate) {
  console.log("The API date is before the current date.");
} else {
  console.log("The API date is after the current date.");
}

    I hope my answer is clear to you

    Comparing date strings is enough, but you should add your timezone offset:

    const d = new Date("2023-07-14"); // will be parsed to a UTC date
d.setMinutes(d.getMinutes() + d.getTimezoneOffset());
console.log(d.toString())

console.log('is today:', d.toDateString() === new Date().toDateString());

    You can get the current date as a string in YYYY-MM-DD format like this:

    const currentDate = (new Date()).toISOString().split('T')[0].toString();
console.log(currentDate);

    Then simply compare with the API date.

    first you should but object in a variable then you should use(>, <, =, and >=) and don’t use(==, !=, ===, or !==)

    check this link for more info : https://sentry.io/answers/how-to-compare-two-dates-with-javascript/

    let date1 = new Date("2023-07-14")

let date2 = new Date("2023-07-14")


if(date1 = date2){
  console.log('yes')
}

    You should first convert the date from the API into a Date object and then compare the parts of the date. Like as follows:

    let apiDate = "2023-07-14";
let current = new Date();

// Convert API date to Date object
let apiDateObj = new Date(apiDate + "T00:00:00");

function checkDates(current, apiDateObj) {
  let tzOffset = apiDateObj.getTimezoneOffset() * 60000;
  let adjustedDateObj = new Date(apiDateObj.getTime() - tzOffset);

  if (adjustedDateObj.toDateString() === current.toDateString()) {
    return "Same date";
  } else {
    return "Different dates";
  }
}

console.log(checkDates(current, apiDateObj), "checkDates");
