I wanted to display a simple array's items on the console, using foreach. It dispalys all the items(it's OK), but it displays "cars : undefined" at the end.
I dont want to display "cars : undefined", but only the 3 items of the array.
How to do ?

```js
var cars = [{
    year: 2011,
    type: "Volvo"
}, {
    year: 1999,
    type: "Volvo"
}, {
    year: 2003,
    type: "Volvo"
}];
console.log("1");

console.log("cars : " + cars.forEach(a => console.log(a)));
console.log("2");
```
