Script Preparation code:

window.foo = [{id: 1, name: 'suh'}, {id: 2, name: 'asd'}];
window.bar = [{id: 2, name: 'asd'}, {id: 1, name: 'suh'}];

Tests:

native filter includes
const abc = foo.map((x) => x.id) ?? []; const xyz = bar.map((x) => x.id) ?? []; !(abc.length !== xyz.length || abc.filter((id) => !xyz.includes(id)).length > 1);
JSON.stringify
JSON.stringify(window.foo) === JSON.stringify(window.bar);
