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

To use the setHours function from date-fns in JavaScript, you can follow these steps:

1. First, install the date-fns library in your project using a package manager like npm or yarn.

   npm install date-fns
   21 chars
   2 lines

2. Next, import the setHours function in your JavaScript code.

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

3. setHours is a function that takes two arguments - a Date object, and an integer representing the desired hour value.

   index.tsx
   const myDate = new Date(); // create a new Date object
   const updatedDate = setHours(myDate, 5); // set the hour to 5
   117 chars
   3 lines

   Note that the setHours function returns a new Date object, instead of modifying the original one.

4. You can also use the third parameter of setHours to set the minutes, seconds, and milliseconds values along with the hour value.

   index.tsx
   const myDate = new Date();
   const updatedDate = setHours(myDate, 5, 30, 0, 0); // set the time to 5:30am
   104 chars
   3 lines

   In this example, the second argument represents the desired hour value (5), the third argument represents the desired minutes value (30), and the fourth and fifth arguments represent the desired seconds and milliseconds values (both set to 0).

That's how you can use the setHours function from date-fns in JavaScript to set the hour value of a Date object.
