AngularJS Promises with $q

[@SuperNirupam]

Please, explain in details like whats var q = $q.defer() means , and how its different from $http and benefits etc

[@mohibwasay5102]

Awesome Illustration. Thanks Joe.! Was seriously having trouble in getting into promises! :D

[@JoeMaddalone]

My example was pretty simplistic, but the benefit is design. Consider if the promise was not using the same function over and over, but a series of tasks that upon an error can bypass all other tasks to return an error without the need for dozens of callbacks. pseudo code here: getUser('M') .then(f(u){ return u.Comment()}) .then(f(c){if(c.Good){return goodResp()} else {return badResp()}}) .then(f(resp){return Post(resp)}) .then( f(resolve){log("Posted")}, f(err{log(err)} )

[@FabianLopez_lomba]

which plugin do you use for angular autocomplete?

[@JoeMaddalone]

I actually have 3 installed: AngularJS: sublime.wbond.net/packages/AngularJS AngularZen: sublime.wbond.net/packages/AngularZen Angular Snippets: sublime.wbond.net/packages/AngularJS%20Snippets Probably some conflicts happening in there somewhere, but... you asked. :)

[@FabianLopez_lomba]

Joe Maddalone I'll check them out, nice intro to promises. They don't look so scary now!

[@SreekanthKarini]

Very clear explanation about what actually $q does, it's helped a lot. may i know is this synchronous calling?

[@StevenBenjamin]

Thank you! - This is the best tutorial on promises yet!

[@heymauriciosoares]

Hello Joe, great video thanks! Let me ask you one thing (i hope it doesn't sound dumb kkk)... what would be a real case usage of promises? for example, what would that help in a real application? Because i can't see why would I use promises instead of a simple recursive function which returns a value based on its conditions... I don't think i got the real purpose of using it... :/ Thanks!

[@francescopiazza4882]

I didn't catch what's good in Promises...

[@miroslavmatovic]

Thank you. This was a very nice and concise tutorial. Q: Regarding line "return q.promise;", I have a question: I have seen it written as "return q.$promise;". What is the difference between .promise and .$promise ?

[@eternoaprendiz1723]

Excelent demostration, make me understand what more than 10 links can't explain me on letters thank you

[@nemiltimbadia7134]

Awesome...Couldn't get it from other sources...Super clear here....

[@johnh7581]

Thanks good stuff. I understand $q now with your example - but how would it look like without using the promise spec in this case I was wondering - in order to gain more clarity. I was trying it out with a jsbin - but I think I am missing something in the logic. jsbin.com/bedih/1/edit - any feedback would be great.

[@remariorichards8237]

You seriously need to explain your stuff man, all u do is type .Really nothing else

[@rajeshwarchinna]

it's like try catch error handling

[@snopocatepetl]

good video, but a messy programming style, mixing colons and not.

[@hiddenblade999]

I was so confused by $q until I watched this demo like 3 times. Thank you.

[@BULLSHXTYT]

This one is a bit harder than other tutorials, I don't quite know what q is but I will check it out myself. Angular is freaking awsome!

[@ktaakash]

OMG, why on earth are you in such a hurry?

[@HindiSongsHITS]

Great video series on Angular.

[@heymauriciosoares]

wow i guess you are right! I just keep learning with your tutorials hahaha Thanks Joe!

[@ajaykoranne3735]

Straightforward and simple to understand video. Very good!

[@orz5516]

angular.?

[@amitavroydev]

Very helpful and nicely explained. Now finally I know $q and how defered works :) Thanks

[@chetanpl]

Very very clearly my concept.

[@SusanElliottSim]

Thanks for this. It helped me more than the web pages that I've been reading.

[@christophermagana1017]

Yeah i dont understand what you're doing. This should have already pretty much been typed out and you go through explaining it.

[@davidgonzales-ec8bo]

perfect. Just helped me clarify my understanding of promises. best yet acutally.

[@JoeMaddalone]

Really glad it helped! Thanks.

[@TheKarantan]

Douglas wouldn't be happy to see all these missing semicolons :)

[@DeusGladiorum]

Why do you sound like John Goodman?

[@SuperYouVIN]

Thank you for this tutorial. A very good example. I could see the usefulness of promises

[@ThijsErends]

Awesome explanation, Thank you for the effort you put in to your videos

[@jcgofredo2239]

Bookmarked* :)

[@rohit-ld6fc]

a better example is what was needed..

[@girishvarma8813]

Man, first explain what is the problem and why we use $q. Then go to how to implement. Any one can get code from internet.

[@Nikhilkumar-qd3oq]

i couldn't understand

[@SaiPrakash16]

Really helpful! good presentation..

[@David-ol7zz]

I got it finally working. Thank you very much, very good video.

[@raffaellafico7652]

Thanks

[@TheAlgerianDz]

Thank you !!

[@Dev_Everything]

Great job sir!!!!. Thank you!

[@kuraibankusu]

Thank you for this!

[@TheAkhilchalla]

Awsome video helped me a lot

[@louisik1]

lost me at 4:30

[@ktalovmorx8307]

Hey hermano, soy un analfabeto...puedes explicar mejor, osea un ejemplo mas practico..? Para que haria tanto para tan poca cosa?

[@aakashggujju]

Awesome 😊

[@narasimharao1537]

cool this helped me

[@Ricardo8605br]

Muito legal!

[@neerajchaudhary4079]

Joe... I think its tutorial for viewers like me who are new to Angular. We understand you knew the stuff but better to explain others in simple and easy manner rather then creating the messy and complex things. Really out of sense of understanding.

[@kothuriraogopi8584]

super

[@dewiwilliams4970]

Disappointing to see you are creating professional videos and your copy of Sublime is unregistered.

[@roach_iam]

+Dewi Williams Why spend $50 when you can just use the unregistered version, which has all features for free?

[@LO000L]

+Kyle Roach To support the developer of sublime? Lol.
