Including variable that can be calculated at build time

[jensmeindertsma]

If I have a value that can be calculated at build time, how do I make sure it is? Right now I'm doing the calculation just before a page function, like:

let years = [2017, 2020, 2025, 1996];
years = years
  .filter((year, index) => years.indexOf(year) === index)
  .sort((yearA, yearB) => {
    return yearA < yearB ? 1 : -1;
  });

const Home = () => {
  return <>{years}</>

Is this the way I should do it? I know this doesn't need to go inside the page function, but where else should it go if it doesn't fit here?

This data would be better computed within getStaticProps so that the code could be eliminated.
