check if difference between two dates is more than a year in javascript

To check if the difference between two dates is more than a year in JavaScript, you can convert the two dates to timestamps and then compare their difference in seconds. One year is equivalent to 31536000 seconds.

Here's an example code snippet that demonstrates this approach:

index.tsx
const date1 = new Date('2020-01-01');
const date2 = new Date('2021-12-31');

const diffInSeconds = Math.abs(date2.getTime() - date1.getTime()) / 1000;
const oneYearInSeconds = 31536000;

if (diffInSeconds > oneYearInSeconds) {
  console.log('The difference between dates is more than a year.');
} else {
  console.log('The difference between dates is less than a year.');
}

In this example, we are comparing date1 and date2. We first calculate the difference between the two dates in seconds using the getTime() method, which returns the timestamp of the date. We then check if the difference is greater than one year in seconds, and log a message accordingly.
