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

The addHours function from date-fns is used to add a certain number of hours to an existing Date object.

To use the addHours function, we need to:

1. Install date-fns via npm or yarn:

   index.tsx
   npm install date-fns
   21 chars
   2 lines

   or

   index.tsx
   yarn add date-fns
   18 chars
   2 lines

2. Import the addHours function:

   index.tsx
   import { addHours } from 'date-fns';
   37 chars
   2 lines

   or

   index.tsx
   const { addHours } = require('date-fns');
   42 chars
   2 lines

3. Call the addHours function with the date object and the number of hours to add:

   index.tsx
   const date = new Date();
   const hoursToAdd = 3;
   const newDate = addHours(date, hoursToAdd);
   console.log(newDate);
   113 chars
   5 lines

   In the above code block, we create a new Date object and store it in the date variable. We also specify the number of hours to add to this date using the hoursToAdd variable. We then pass both variables to the addHours function which returns a new Date object with the specified hours added to it. Finally we log the new date object to the console.
