Check if multiple objects are equal

const isEqual = (...objects) => objects.every((obj) => JSON.stringify(obj) === JSON.stringify(objects[0]));

const isEqual = (...objects: object[]): boolean =>
    objects.every((obj) => JSON.stringify(obj) === JSON.stringify(objects[0]));

isEqual({ foo: 'bar' }, { foo: 'bar' }); // true
isEqual({ foo: 'bar' }, { bar: 'foo' }); // false
