Multiple keys with same value in javascript object

Question

so I'm trying to replicate an HTTP payload which has two same keys with different values.

const x = {};
x['house'] = 'table';
x['house'] = 'food';

The above doesnt work. Is there another alternative?

Answer 1

The usual way to do that is to use an array :

const x = {};
x.house = ["table", "food"];

Or

const x = {
    house: ["table", "food"]
};

You could also use a Set :

const x = {
    house: new Set()
};
x.house.add("table");
x.house.add("food");

or

const x = {
    house: new Set(["table", "food"])
};

I've used dot notation above, but you can use brackets notation as you did in your question if you prefer:

const x = {};
x["house"] = ["table", "food"];
