Script Preparation code:

const obj = {A: 'A', B: 'B', C: 'C', D: 'D', E: 'E', F: 'F', G: 'G', H: 'H', I: 'I', J: 'J'};

const dataArray = ['A', 'B', 'C', 'D', 'E', 'F', 'G', 'H', 'I', 'J'];
const dataSet = new Set(dataArray);

const proxyFixedArray = new Proxy(obj, {
    ownKeys(t) {
        return dataArray;
    }
});
const proxySpreadSet = new Proxy(obj, {
    ownKeys(t) {
        return [...dataSet];
    }
});
const proxyArrayFromSet = new Proxy(obj, {
    ownKeys(t) {
        return Array.from(dataSet);
    }
});
