        cor: "Branco",
        tamanho: "Queen"
    },
    sku: 133
}]
};

Answer 1

Ok, but first let’s create a valid object, because the stated question is not.

var produtos = {
    skus:[{
        especificacao: {
            cor: "Azul",
            tamanho: "Queen"        
        },
        sku: 132
    }, {
        especificacao: {
            cor: "Branco",
            tamanho: "Queen"
        },
        sku: 133
    }]
};

To search for an object in an array, you can use the method find. The find method takes a callback, and invokes this callback by passing by parameter each object of your array, just return true for when the object meets its criteria.

var skuEncontrado = produtos.skus.find(sku => sku.especificacao.cor === 'Azul' && sku.especificacao.tamanho === 'Queen');

You can use the filter, would be something like:

var produtos = {
    skus: [
        {
            especificacao: {
                cor: "Azul",
                tamanho: "Queen"
            },
            sku: 132
        },{
            especificacao: {
                cor: "Branco",
                tamanho: "Queen"
            },
            sku: 133
        }
    ]
};

var list = produtos.skus.filter(function(item){
    return (item.especificacao.cor == 'Azul' && item.especificacao.tamanho == 'Queen');
});

console.log('Lista de Produtos: ', list);
