/**
|
|
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
|
|
});
|
|
```
|
|
