JavaScript Array Methods .find()

const list = [5, 12, 8, 130, 44];
// a find metóduson belül a number egy paraméter
// azért nem szükséges köré a zárójel, mert csak egy paramétert adunk át
// minden más esetben így kell írni:
// const found = list.find((index, number) => number > index);
const found = list.find(number => number > 10);
console.log(found);
// --> 12
