如何在Javascript中分配具有相同属性的多个对象

Question

How do you create numerous objects under the same method with identical properties in Javascript?

Im familiar with how to create objects in Javascript as such:

var myCar = new Object(); 
myCar.make = 'ford';
myCar.model = 'mustang';
myCar.year = 1969;

But what if I wanted to assign an array to an object and have all the values have the same properties?

Arr = [1,2];
Arr[i].value === Arr[i]
Arr[j].value === Arr[j]
Arr[i].value === Arr[j].value
!Arr[i].hasOwnProperty('value')
!Arr[j].hasOwnProperty('value')

where as the value method is the same and not unique to the object

object1.hasOwnProperty('value'); //Evaluates to `false`

I'm used to programming in Python so my first guess is to create a dictionary and dynamically assign the array to the values but I'm not sure how to work with properties in Javascript objects.

Edit: Mistakenly included '==' operators when I meant to use '===' operators.

Answer 1

You need to do it like this - by creating an object. Also use the assignment operator = not comparison operator == :

 let Arr = [1,2]; let i = 0; let j = 1; Arr[i] = { value: Arr[i] }; Arr[j] = { value: Arr[j] }; console.log(Arr); 

 .as-console-wrapper { max-height: 100% !important; top: auto; }

I don't know if this is what you're asking for but you can create your own objects in two ways

function Car (make, model, year) {
    this.make = make;
    this.model = model;
    this.year = year;
}

// you can also add methods using the object's protoype
Car.prototype.isNissan() {
    return this.make == 'Nissan';
}

In modern syntax you can create classes

class Car {
    constructor(make, model, year) {
        this.make = make;
        this.model = model;
        this.year = year;
    }

    methodName() {
        // method body
    }
}

And use it in your code like so

let myCar = new Car('Nissan', 'some model', 2018);
