Well, if John Smilga gives an explanation on something, understanding is guaranteed. Thanks for another demystification.

[@CoderDmitri]

John Smilga for president!

[@juicetheballer]

I appreciate all these videos

[@udaysharma444]

Best ever explanation

[@MIDNightPT4]

Gifted teacher… Thanks!!

[@CodingAddict]

Glad it was helpful!

[@Jacksons_are_jackson]

brillant teacher omg

[@faycal7929]

it's like callback hell ... but in a fancy way!

[@mollenbu77]

It's promise hell

[@youcefkellali751]

the best one in javascript

[@sohamvishwas6795]

Thank you for sharing your knowledge

[@my_vk_vlogs]

Nice video to understand the promise

[@codex8797]

Nice bro.

[@AhmedIbrahim-fi2so]

ooo thanksss ❤️❤️❤️

[@CodingAddict]

Welcome 😊

At 11:50 line 14, the last call off addColor didn’t receive the 4th parameter "data".
Doesn’t JavaScript complain about this?

[@Han-ve8uh]

Mismatch between interface of javascript parameters and arguments passed are fine. Extra arguments are ignored, missing arguments are set to undefined if no defaults setup

[@ozankurucu6261]

Thanks

[@saulchipwayambokoma3213]

My headings are still going ahead at their pre-set times. they are not waiting for the previous one to carry out it's action first

[@ramborb8795]

Can somebody tell me, on MENU project, why the border on the filter buttons have the border color left and up gold and right and down black ? I inspected the buttons, I changed the colour, but still half has a darker colour that the other. Thank you

[@ramborb8795]

Sorry, I asked the question at wrong video. I had the videos in a playlist and a new video started

[@AhmedIbrahim-fi2so]

i think i know how to do that 🤓🤓🤓 ! we can say resolve ( data ) in the finctio ! and then each time .. we pass the next color in the parameter of ( then ) ! as a data ... then inside the (then ) we pass the data insted of the color argument

[@rentalabharadwaja8013]

Can't we do the same functionality without promise , only with setTimeout??

[@virusnetic]

yes you can but then it will be a callback hell

[@anatutech]

This looks like Promise Hell to me.😁

[@virusnetic]

It's actually not because we don't have rewrite the same functionalities again and again
we can simply call an function for that

[@anandoganiya9070]

In .then( ) if you don't callback and directly invoke the addColor( ) then even after commenting out resolve the program works fine ,why is that happening?

[@lamb8086]

The program didn’t work fine. Once he commented out the resolve, addColor only worked the first time it was called and never made it to the first .then(). He said if you console.log you would see that the promise would still be pending.

[@anandoganiya9070]

@@lamb8086 you didn't get my point

[@anandoganiya9070]

@@fugitivemind it gets invoked after you trigger the event ,nothing is change only i invoke the function inside .then( ) like .then( addColor( parameters...) ) , that mean even after commenting resolve .then( ) gets executed; it proves that it does not depend on resolve( ) call but yeah the state is still pending;

[@CodingAddict]

Program does not work fine, check the sequence. And the reason for that is because with your suggested setup we invoke addColor(params) right away instead of passing as callback. .then(addColor(params), if you will pass it as a reference .then(addColor), you will see that while the promise is pending it's not going to be invoked.
