/**
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
});
```

/**
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
});
```
