.getHours()

Called from an instance of the Date class, will return the hour according to the local time.

myDate.getHours();

The return value of getHours() will only be an integer number between 0 and 23, meaning the hour according to the local time.

const today = new Date('June 25, 2021 13:41:30');

if (today.getHours() === 10) {
  console.log('It is 10 in the morning now.');
} else {
  console.log('It is not 10 in the morning now.');
}

// Output: It is not 10 in the morning now.
