let array = [];
people.forEach((elem) => {
// elem before age to target
if (elem.age > 18) {
array.push(elem); // each array elem > 18 is "pushed" inside the new array
// console.log(array); nope : messes things up
} else {
(""); // no need to declare this through console.log
}
});
console.log(array); //and there you have it : filtered array
