            categories[product.category] = {
                    items: []
            };
    }
  });
    products.forEach(product => {
    Object.keys(categories).forEach(category => {
            if (product.category === category) {
                    categories[category].items.push(product);
            }
    });
 });
   console.log(categories);

var categories=products.map(product=>product.category)
var result=categories.map(category=>{
 return{'category':category,'products':products.filter(product=>product.category==category)}
    })
