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

To use the setDate function from the date-fns library in TypeScript, you can first install the library and its types by running the following command in your project directory:

index.ts
npm install date-fns @types/date-fns

2 lines

Then, you can import the setDate function from date-fns and use it in your TypeScript code as follows:

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

const date = new Date();
const newDate = setDate(date, 15);

console.log(newDate); // Output: 2021-10-15T00:00:00.000Z

In this example, we first import the setDate function from date-fns. We then create a new Date object and pass it as the first argument to setDate. The second argument is the day of the month that we want to set, which in this case is 15. The setDate function returns a new Date object that has the day of the month set to 15, which we then log to the console.

Note that we also need to import the Date type from TypeScript in order to correctly type the date and newDate variables.
