Check this code

let cars = [{
        name: 'Volvo',
        equipments: [
         { name: 'saddleries', options: [{title: 'leather'}] },
         { name: 'wheels', options: [{title: 'sliver'}] },
         { name: 'motor', options: [] }]
}];

cars.forEach((c) => {
c.equipments = c.equipments.filter(e => e.options.length !== 0);
})
console.log(cars)
