Question

How do i achieve this :

function Vehicle(){
    this.mobility = true;
};
function Car(){};
Car.prototype = new Vehicle();
var myCar = new Car();
console.log(myCar.mobility);

Using objects created with Object literals ?

I know about Object.create() but is there any way like

Car.prototype = new Vehicle();

to achieve that ?

Here’s how you do it using __proto__:

var propertiesToInherit = { 'horsepower': 201, 'make': 'Acura' }
var myCar = {};
myCar.__proto__ = propertiesToInherit;

console.log(myCar.horsepower); // 201
console.log(myCar.make); // Acura

That being said, I would avoid doing this. It looks like it is deprecated
