javascript - 具有键/值对的数组

Question

Is it possible to have a key value pair in arrays in javascript. I'm looking to have something like the following

const array = 
[
'item': 'Jumper', 'price', '160',
'item': 'Shirt', 'price', '50',
'item': 'Cap', 'price', '20',
]

Or is there a better datastructure to use?

Answer 1

Yes, you just make it an array of objects:

 const array = [ {'item': 'Jumper', 'price': '160'}, {'item': 'Shirt', 'price': '50'}, {'item': 'Cap', 'price': '20'}, ] console.log(array);

Answer 2

Use objects. You can do it the way it's shown in @dave's answer, or you can instead use classes :

class Product {
    constructor(item, price) {
        this.item = item;
        this.price = price;
    }
}

const array = [
    new Product('Jumper', 160),
    new Product('Shirt', 50),
    new Product('Cap', 20),
];
