Not override spreaded value

I'm exporting some objects:

const PA28_161 = {
    ...aircraft,
    name: 'Piper Warrior PA28-161',
    weightMaxTakeoffPounds: 2325,
    weightMaxLandingPounds: 2325,
    additionalCategories: [
        {
            name: 'utility',
            weightMaxTakeoffPounds: 1950
        }
    ],
    masses: [
        {
            ...mass,
            name: 'Front Seats',
            armInches: 80.5
        },
        {
            ...mass,
            name: 'Fuel',
            armInches: 95,
            weightMaxPounds: 2179.45
        },
        {
            ...mass,
            name: 'Rear Seats',
            armInches: 118.1
        },
        {
            ...mass,
            name: 'Baggage',
            armInches: 142.8,
            weightMaxPounds: 200
        }
    ]
};

export const default_templates = [
    {
        ...PA28_161,
        name: 'OHO YLIL',
        masses: [
            {
                ...mass,
                name: 'Empty Weight',
                weightPounds: 1521.45,
                armInches: 86.18
            }
        ]
    }
];

How can I add a mass to masses without overriding the spreaded masses?

You can spread the current masses property

masses: [...masses, {}]

masses: [...masses, {}]

Or, push to it upfront:

masses.push({})

masses.push({})

how the frick did I not think of that 🤣

I guess you're technically overwriting it... but with itself so does it count? 🤔

ZachOP•16mo ago

went with another solution in the end might refactor back to what I had idk
