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

const quarters = 8;
const years = quarterstoYears(quarters);

console.log(years); // Output: 2

In the above code, we first import the quarterstoYears() function from date-fns. Then we assign a value of 8 to the quarters variable. We pass this value as an argument to the quarterstoYears() function to get the total number of years represented by 8 quarters. Finally, we log this value to the console, which outputs 2.

Note that the quarterstoYears() function takes a single argument, which is the number of quarters to convert to years.
