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

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

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

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

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 2 жыл бұрын
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

Can't we do the same functionality without promise , only with setTimeout??
@virusnetic 8 ай бұрын
yes you can but then it will be a callback hell
@anandoganiya9070 3 жыл бұрын
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 3 жыл бұрын
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.

@@fugitivemind87 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 3 жыл бұрын
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.
