The addWeeks function takes two arguments:

1. A date object or a string representing a date
2. A number representing the number of weeks you want to add (can be a negative number to subtract weeks)

Here's an example of how to use the addWeeks function to add two weeks to the current date:

index.tsx
const now = new Date();
const twoWeeksLater = addWeeks(now, 2);

console.log(twoWeeksLater); // output: 2022-05-27T13:28:47.856Z

In this example, the now variable is a date object representing the current date and time. The addWeeks function is used to add two weeks to the current date, and the result is stored in the twoWeeksLater variable. The console.log statement outputs the result, which is the date and time two weeks from now.

That's it! You can now use the addWeeks function from date-fns library to add or subtract weeks from a date object in JavaScript code.
