// I'd like to do this:
try {
    var products = _do(getProductsPromise); 
    
    console.log('from task: ', products);
} catch (err) {

}

// Instead of this:
getProductsPromise
    .then(function (products) {
        console.log('from callbacks: ', products);
    })
    .catch(function (err) {
        throw err;
