+
+ /**
+ The primary way of interacting with a promise is through its `then` method,
+ which registers callbacks to receive either a promise's eventual value or the
+ reason why the promise cannot be fulfilled.
+ ```js
+ findUser().then(function(user){
+ // user is available
+ }, function(reason){
+ // user is unavailable, and you are given the reason why
+ });
+ ```
+ Chaining
+ --------
+ The return value of `then` is itself a promise. This second, 'downstream'
+ promise is resolved with the return value of the first promise's fulfillment
+ or rejection handler, or rejected if the handler throws an exception.
+ ```js
+ findUser().then(function (user) {
+ return user.name;
+ }, function (reason) {
+ return 'default name';
+ }).then(function (userName) {
+ // If `findUser` fulfilled, `userName` will be the user's name, otherwise it
+ // will be `'default name'`
+ });
+ findUser().then(function (user) {
+ throw new Error('Found user, but still unhappy');
+ }, function (reason) {
+ throw new Error('`findUser` rejected and we're unhappy');
+ }).then(function (value) {
+ // never reached
+ }, function (reason) {
+ // if `findUser` fulfilled, `reason` will be 'Found user, but still unhappy'.
+ // If `findUser` rejected, `reason` will be '`findUser` rejected and we're unhappy'.
+ });
+ ```
+ If the downstream promise does not specify a rejection handler, rejection reasons will be propagated further downstream.
+ ```js
+ findUser().then(function (user) {
+ throw new PedagogicalException('Upstream error');
+ }).then(function (value) {
+ // never reached
+ }).then(function (value) {
+ // never reached
+ }, function (reason) {
+ // The `PedgagocialException` is propagated all the way down to here
+ });
+ ```
+ Assimilation
+ ------------
+ Sometimes the value you want to propagate to a downstream promise can only be
+ retrieved asynchronously. This can be achieved by returning a promise in the
+ fulfillment or rejection handler. The downstream promise will then be pending
+ until the returned promise is settled. This is called *assimilation*.
+ ```js
+ findUser().then(function (user) {
+ return findCommentsByAuthor(user);
+ }).then(function (comments) {
+ // The user's comments are now available
+ });
+ ```
+ If the assimliated promise rejects, then the downstream promise will also reject.
+ ```js
+ findUser().then(function (user) {
+ return findCommentsByAuthor(user);
+ }).then(function (comments) {
+ // If `findCommentsByAuthor` fulfills, we'll have the value here
+ }, function (reason) {
+ // If `findCommentsByAuthor` rejects, we'll have the reason here
+ });
+ ```
+ Simple Example
+ --------------
+ Synchronous Example
+ ```javascript
+ let result;
+ try {
+ result = findResult();
+ // success
+ } catch(reason) {
+ // failure
+ }
+ ```
+ Errback Example
+ ```js
+ findResult(function(result, err){
+ if (err) {
+ // failure
+ } else {
+ // success
+ }
+ });
+ ```
+ Promise Example;
+ ```javascript
+ findResult().then(function(result){
+ // success
+ }, function(reason){
+ // failure
+ });
+ ```
+ Advanced Example
+ --------------
+ Synchronous Example
+ ```javascript
+ let author, books;
+ try {
+ author = findAuthor();
+ books = findBooksByAuthor(author);
+ // success
+ } catch(reason) {

+ }
+ ```
+ Errback Example
+ ```js

+ }
+ function failure(reason) {
+ }
+ findAuthor(function(author, err){
