// Promises can only resolve (return) a single value
// Sometimes, you want to collect multiple values as you progress through a promise chain
// e.g. Customer, Product, Basket, Payment Details
// 
// I can only think of three options for handling this type of scenario (below)
// NB: Assume that FOO, BAR & BAZ are the result of some complex action (DB query etc.)
// 
// What are the Pro's & Cons? 
// Are there others?

// Wrong ways to use Errors in Promises

// Passes Error constructor to next step in Promise chain
Promise.resolve('foo').then(val => {
    return Error('Bad Thing 1');
}).then(val => {
    console.log('LOG 1', val);

Basics of the Unix Philosophy
=============================

Rule of Modularity:     Write simple parts connected by clean interfaces

Rule of Clarity:        Clarity is better than cleverness

Rule of Composition:    Design programs to be connected with other programs

Rule of Separation:     Separate policy from mechanism; separate interfaces from engines
