To compare Unix timestamps in JavaScript, follow these steps:

  1. Convert the timestamps to Date objects using the new Date() constructor. The new Date() constructor in JavaScript accepts a timestamp as an argument.

const timestamp1 = 1609459200; // Unix timestamp in seconds
const timestamp2 = 1609545600; // Unix timestamp in seconds

const date1 = new Date(timestamp1 * 1000); // Multiply by 1000 to convert seconds to milliseconds
const date2 = new Date(timestamp2 * 1000);


  1. Use the comparison operators (<, >, <=, >=, ===, !==) to compare the two dates.

if (date1 < date2) {
  console.log('Timestamp 1 is earlier than timestamp 2');
} else if (date1 > date2) {
  console.log('Timestamp 1 is later than timestamp 2');
} else {
  console.log('Timestamps are equal');
}


Note that multiplying the timestamp by 1000 is necessary because JavaScript requires the timestamp to be specified in milliseconds.
