how to use the isequal function from date-fns in javascript

To use the isEqual function from the date-fns library in JavaScript, you need to first install the library using npm or include it in your HTML file using a CDN link. After installing or including the library, you can import the isEqual function and use it in your code as follows:

index.tsx
// Import the isEqual function from date-fns
import { isEqual } from 'date-fns';

// Define two date objects to be compared
const date1 = new Date('2021-12-31T23:59:59');
const date2 = new Date('2021-12-31T23:59:59');

// Compare the date objects using the isEqual function
if (isEqual(date1, date2)) {
  console.log('The two dates are equal');
} else {
  console.log('The two dates are not equal');
}

In this example, we first import the isEqual function from the date-fns library using the ES6 destructuring syntax.

We then define two date objects date1 and date2 with the same date and time.

Finally, we pass these two date objects to the isEqual function, which returns true if both date objects have the same date and time, and false otherwise.

The code then uses an if-else statement to print a message to the console indicating whether the two dates are equal or not.
