Setup

const found = [];

const batch = Array.from({ length: 1000 }, (_, i) => ({
  WINDOWKEY: `windowKey${i + 1}`,
}));

// Fonction pour générer un nombre aléatoire entre min et max (inclus)
function getRandomInt(min, max) {
  return Math.floor(Math.random() * (max - min + 1)) + min;
}

// Génération du tableau de 14 entrées
let results = [];
for (let i = 0; i < 14; i++) {
  let randomNum = getRandomInt(1, 1000);
  results.push({ windowKey: `windowKey${randomNum}` });
}

Teardown

console.log(found);
