2 lines

Then, you can use the function to set a date to a specific ISO week number like this:

index.ts
const date = new Date('2022-01-01'); // create a new date object

const weekNumber = 24; // the ISO week number to set the date to

const newDate = setISOWeek(date, weekNumber); // set the date to the specified ISO week number

In this example, the setISOWeek function takes two arguments: the date to be modified and the ISO week number to set the date to. The function returns a new Date object with the week number set to the specified value.

Note that the setISOWeek function does not modify the original Date object, but instead returns a new Date object with the modified week number.
