Run a bunch of asynchronous functions and get all the values at once at the end!
var all = require('./')
function someAsyncThing(cb) {
setTimeout(function() {
cb(null, 'some sweet value')
}, 50)
}
function someOtherAsyncThing(cb) {
setTimeout(function() {
cb(null, 'some other value')
}, 10)
}
all({
someValue: someAsyncThing,
whatever: someOtherAsyncThing
}, function(err, results) {
results.someValue // => 'some sweet value'
results.whatever // => 'some other value'
})
all({
tmp: fs.stat.bind(fs, '/tmp'),
broken: fs.stat.bind(fs, '/tmp/doesntexist/asfarasIknow')
}, function(err, results) {
startsWith(err.message, 'ENOENT') // => true
})
