Next, you can use the addMonths function to add a certain number of months to a date:

index.tsx
const currentDate = new Date(); // get the current date
const futureDate = addMonths(currentDate, 6); // add 6 months to the current date
console.log(futureDate); // output: 2022-03-07T13:24:45.115Z (currentDate = 2021-09-07T13:24:45.115Z)

In the example above, the addMonths function is used to add 6 months to the current date. The resulting date is stored in the futureDate variable, and then printed to the console.

Note that the addMonths function returns a new Date object, and does not modify the original date object.
