// Define coordinates.
const parisLatitude = 48.864716

const parisLongitude = 2.349014

const tokyoLatitude = 35.67619190

const tokyoLongitude = 139.65031060

// Compute the distance.
const distance = haversine(parisLatitude, parisLongitude, tokyoLatitude, tokyoLongitude);

// Note: The result is in kilometers, rounded down to the nearest integer.
