Output showing Undefined using find array helper in javaScript

Question

So, here is the code which is using find helper in javaScript and supposed to return a value but instead of that it is showing undefined.

function Car(model) {
this.model = model;
}
var cars = {
 new Car('Buick'),
 new Car('Camaro'),
 new Car('Focus')
};
cars.find(function(car){
 return car.model === 'Focus';
});

I am running this code in VB and the output supposed to be Focus but it is showing undefined.

Your cars variable needs to be an array not an object as you don't have keys, just a list. Here is a working example:

function Car(model) {
  this.model = model;
}
var cars = [
  new Car('Buick'),
  new Car('Camaro'),
  new Car('Focus')
];
console.log(cars.find((car) => car.model === 'Focus'));
