just a convention unfortunately, but if adhered to religiously they make writing asynchronous code much, much, much less painful

basically a 'promise' is an object that calls a callback when some operation has finished (or failed).

it has sensible semantics (like, if you say "hey call this function when you're done" on a promise that's already been resolved, that function still gets called instead of being forgotten about), and having a common api for every thing-that-calls-a-callback-when-it's-done means that you can get lots of cool utility functions to manipulate promises and avoid your async code turning into callback hell

here's a bad example probably. sorry of the php tags, wanted some highlighting.

php:

<?
    function upgradeUser () {
        return Q.Promise( function ( resolve, reject, notify ) { // this makes the function return a promise, and passes 3 functions into it
            getUser( req.userToken, function ( err, user ) {
                if ( err )
                    reject( new Error( "Could not find any user." ) // this uses the reject functions passes in above, 
                    // which ends the function and sends this message along
                    
                performUpgrade( user, function( err, success ) {
                    if ( err )
                        reject( new Error( "Could not upgrade this account." ) ) // same as above. but keep in mind 
                        // it doesn't just return this value, it returns it and the status that it failed
                        
                    resolve( success ) // ends the function upgradeUser(), returns the value (same as above) 
                    // BUT with the status that "it worked"
                })
            })
        })
    }
    
    upgradeUser()

    upgradeUser()
    // .then( someOtherFunction ) -- just showing you can add many more functions to the chain, each passing the resolve() value of the last to the next
    .then( function ( success ) { // or pass it into an anonymous function like this
        return res.json( "Account upgraded" )
    }, function ( err ) { // the second function, separated by comma, will be the error, and only triggered if there is a reject() value sent somewhere above
        console.error( err )
        return res.json( err.message )
    })
?>

notice that i've nested the "resolve" and "reject" functions pretty deep in the original upgradeUser() function. usually, without promises, you have to "return" values all the way up the chain of functions. with promises, it doesn't matter where you call resolve(), it will return that value and finish the function.

at the bottom you chain the functions together with the really easy ".then()". unfortunately, though, you have to do this. i can't do

code:

success = upgradeUser()

because .then(), or .spread() or other promise functions, will translate the Promise object being returned into the value put into resolve() only if there is one. if there's an error, it just jumps down the chain of .then()'s to the functions returning the error and shows the first value to be passed into reject().

you can also do

code:

	Q.all( [ saveImage1(), saveImage2() ])
	.spread( function( image1, image2 ) {
		return res.json( { "image1": image1,
		"image2": image2
		})
	})

which will run the two functions saveImage#() in parallel, and actually return the resolve() values from each (they should be promise functions like the one i made above) as an Array. the lovely .spread() function will split the array into separate values, which i then named image1 and image2.

i hope someone likes reading this cause it took me forever to understand promises and i probably still but this is what i wish someone told me from the start

eh. proper async/await support is a strictly better interface, but promises at least papers over the callback hell, and with yield they can even be tolerable to write

the big problem with the js promises i've seen is they tend to swallow errors because there's nowhere to raise them
with an async statement you have a call point where you can just raise the exception as normal, with a proper stack trace and everything
promise stack traces tend to suck, when you even get them

fart simpson posted:

a promise is sorta lifting the callback into the return argument, so you can compose things through method chaining, rather than nested functions.

i.e

get_a_page().then(do_a_thing).then(some_other_thing)

instead of

get_a_page(function callback(v,e) {do_a_thing(v, function callback2(v,e) { some_other_thing(v) }) })

the reason that it is more than just a future or observable value, is that a promise is something you can pass in to a thing that expects a callback

p = Promise()
get_a_page(p.callback)
p.then(....)
