Script Preparation code:

const arr = Array(500).fill(null);
var parents = arr.map(() => {
    return {
        children: arr.map((value, index) => ({value, selected: index % 2})),
    };
});

Tests:

Not optimized
let out = []; parents.forEach(parent => { const selected = parent.children.filter(child => child.selected).map(child => child.value); out = [...out, ...selected]; });
Optimized
const out = []; parents.forEach(parent => { parent.children.forEach(child => child.selected && out.push(child.value)); });
