-[.any](http://bluebirdjs.com/docs/api/promise.any.html),

-[.some](http://bluebirdjs.com/docs/api/promise.some.html).

+- [Promise.all](http://bluebirdjs.com/docs/api/promise.all.html)([p]) - expect all to pass
+- [Promise.some](http://bluebirdjs.com/docs/api/promise.some.html)([p], count) - expect `count` to pass
+- [Promise.any](http://bluebirdjs.com/docs/api/promise.any.html)([p]) - same as `some([p], 1)`
+- [Promise.race](http://bluebirdjs.com/docs/api/promise.race.html)([p], count) - use `.any` instead
+- [Promise.map](http://bluebirdjs.com/docs/api/promise.map.html)([p], fn, options) - supports concurrency
 
 ```js
 Promise.all([ promise1, promise2 ])
-  .then(function (results) {
+  .then(results => {
     results[0]
     results[1]
   })
 
 // succeeds if one succeeds first
 Promise.any(promises)
-  .then(function (result) {
+  .then(results => {
   })
 ```
 
+Use [Promise.map](http://bluebirdjs.com/docs/api/promise.map.html) to "promisify" a list of values.
+
+```js
+Promise.map(urls, url => fetch(url))
+  .then(...)

 Usually it's better to use `.join`, but whatever.
