how to use the addweeks function from the date-fns library in typescript

You can use the addWeeks function from the date-fns library in Typescript by importing the function from the library and providing type annotations for the function parameters and return type.

Here's an example of how to use addWeeks function in Typescript:

index.ts
import { addWeeks } from 'date-fns';

const date = new Date('2021-07-25');
const numberOfWeeksToAdd: number = 2;

const newDate = addWeeks(date, numberOfWeeksToAdd);

console.log(newDate);

In this example, we import the addWeeks function from the date-fns library. We then declare a new Date object with the value of 2021-07-25 and a variable numberOfWeeksToAdd of type number with the value of 2.

We then call the addWeeks function passing in the date object and the numberOfWeeksToAdd variable as arguments. The returned value is assigned to a new variable newDate with the type of Date.

Finally, we log newDate to the console which should output the date object with 2 weeks added to it.

Make sure to install date-fns package in your Typescript project before using the function.
