Using a variable for a property name

Question

When I try this code, I cannot give a const to "option_code" in an object.

const option_code = "option1211";
const product_code = "3344";
const size_code = "44"

var product_data = {
    option_code: size_code,
    quantity: "1",
    product_id: product_code,
}

I want a result like this (option code needs to change) =>

{ option1211:'44', quantity:'1', product_id:'3344' }

Is this possible ?

There is no JSON in this question. Please don't abuse the name. — Heretic Monkey, Jan 19 '22 at 21:49

You're close, you just need to add square brackets around the key name:

var product_data = {
    [option_code]: size_code,
    quantity: "1",
    product_id: product_code,
}

Otherwise, you can do the following:

var product_data = {
    quantity: "1",
    product_id: product_code,
}

product_data[option_code] = size_code;
