Generate many elements inside an array

Question

I want to generate an array with many elements inside.

const a = Array.from({length: 5}, (v, i) => {car:5});
console.log(a)

With the code above, i want to get this:

[
{car:5},
{car:5},
{car:5},
{car:5},
{car:5}
]

...but now i get undefined. It is possible to get what i described using Array.from()?

@Sheelpriy that will create an array with a single object that put in all the slots. Changing one changes all. — VLAZ, Sep 28 '20 at 06:29
@Sheelpriy it's definitely *completely* different from the sample code provided. — VLAZ, Sep 28 '20 at 06:32

If you want to return object from arrow function, wrap it into curly bracket ()

const a = Array.from({length: 5}, (v, i) => ({car:5}));
console.log(a)
