Work in progress. For now its just a collection of notes until I can assemble this into a tutorial.
-use to react to eventual result of async action
-use .then method
-three states: succcess, rejected, pending
asyncLookupPrice(1234).then(function (price) {
console.log('The item costs: ' + price);
return price
})
.then(function (price) {
console.log('Double the price: ' + (price * 2))
})
.catch(function (error){
console.log('Could not find an item with that ID')
})
