Error-tolerant promise map with more bookkeeping (Bluebird)

.js

var bhttp = require("bhttp");

var urls = [
	"http://google.com/",
	"http://yahoo.com/",
	"http://bing.com/" // Ha ha, just kidding who uses Bing anyway :)
];

Promise.try(function(){
	/* There's a faster shorthand for this, but for illustrative purposes, we'll just return the array here and pretend that it was generated by something else, somehow. */
	return urls;
}).map(function(url){
	/* Turn it into an object... */
	return {
		url: url
	};
}).map(function(task){
	return Promise.try(function(){
		return bhttp.get(task.url);
	}).catch(function(err){
		return null;
	}).then(function(response){
		task.response = response;
		return task;
	})
}).filter(function(task){
	return (task.response != null);
}).map(function(task){
	task.body = task.response.body;
	return task;
}).then(function(tasks){
	/* Now `tasks` is an array of tasks, one for each successful URL, and with a `body` property containing the response body. */
});

@vicatcu Thanks, fixed :)
