/**
|
||
|
|
Returns a promise that is fulfilled when all the given promises have been
|
||
|
|
fulfilled, or rejected if any of them become rejected. The return promise
|
||
|
|
is fulfilled with an array that gives all the values in the order they were
|
||
|
|
passed in the `promises` array argument.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var promise1 = RSVP.resolve(1);
|
||
|
|
var promise2 = RSVP.resolve(2);
|
||
|
|
var promise3 = RSVP.resolve(3);
|
||
|
|
var promises = [ promise1, promise2, promise3 ];
|
||
|
|
|
||
|
|
RSVP.all(promises).then(function(array){
|
||
|
|
// The array here would be [ 1, 2, 3 ];
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
If any of the `promises` given to `RSVP.all` are rejected, the first promise
|
||
|
|
that is rejected will be given as an argument to the returned promises's
|
||
|
|
rejection handler. For example:
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var promise1 = RSVP.resolve(1);
|
||
|
|
var promise2 = RSVP.reject(new Error("2"));
|
||
|
|
var promise3 = RSVP.reject(new Error("3"));
|
||
|
|
var promises = [ promise1, promise2, promise3 ];
|
||
|
|
|
||
|
|
RSVP.all(promises).then(function(array){
|
||
|
|
// Code here never runs because there are rejected promises!
|
||
|
|
}, function(error) {
|
||
|
|
// error.message === "2"
|
||
|
|
});
|
||
|
|
```

/**
|
||
|
|
`RSVP.race` allows you to watch a series of promises and act as soon as the
|
||
|
|
first promise given to the `promises` argument fulfills or rejects.
|
||
|
|
|
||
|
|
Example:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var promise1 = new RSVP.Promise(function(resolve, reject){
|
||
|
|
setTimeout(function(){
|
||
|
|
resolve("promise 1");
|
||
|
|
}, 200);
|
||
|
|
});
|
||
|
|
|
||
|
|
var promise2 = new RSVP.Promise(function(resolve, reject){
|
||
|
|
setTimeout(function(){
|
||
|
|
resolve("promise 2");
|
||
|
|
}, 100);
|
||
|
|
});
|
||
|
|
|
||
|
|
RSVP.race([promise1, promise2]).then(function(result){
|
||
|
|
// result === "promise 2" because it was resolved before promise1
|
||
|
|
// was resolved.
|
||
|
|
});
|
||
|
|
```
|
||
|
|
|
||
|
|
`RSVP.race` is deterministic in that only the state of the first completed
|
||
|
|
promise matters. For example, even if other promises given to the `promises`
|
||
|
|
array argument are resolved, but the first completed promise has become
|
||
|
|
rejected before the other promises became fulfilled, the returned promise
|
||
|
|
will become rejected:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var promise1 = new RSVP.Promise(function(resolve, reject){
|
||
|
|
setTimeout(function(){
|
||
|
|
resolve("promise 1");
|
||
|
|
}, 200);
|
||
|
|
});
|
||
|
|
|
||
|
|
var promise2 = new RSVP.Promise(function(resolve, reject){
|
||
|
|
setTimeout(function(){
|
||
|
|
reject(new Error("promise 2"));
|
||
|
|
}, 100);
|
||
|
|
});
|
||
|
|
|
||
|
|
RSVP.race([promise1, promise2]).then(function(result){
|
||
|
|
// Code here never runs because there are rejected promises!
|
||
|
|
}, function(reason){
|
||
|
|
// reason.message === "promise2" because promise 2 became rejected before
|
||
|
|
// promise 1 became fulfilled
|
||
|
|
});
|
||
|
|
```

||

`RSVP.reject` returns a promise that will become rejected with the passed
|
||
|
|
`reason`. `RSVP.reject` is essentially shorthand for the following:
|
||
|
|
|
||
|
|
```javascript
|
||
|
|
var promise = new RSVP.Promise(function(resolve, reject){
|
||
|
|
reject(new Error('WHOOPS'));
|
||
|
|
});

|
||
|
|
promise.then(function(value){
|
||
|
|
// Code here doesn't run because the promise is rejected!
|

|
|
}, function(reason){
|

// reason.message === 'WHOOPS'
|
||
|
|
});
|
||
|

```
|
