Help me with JavaScript!!

[Bitcoinani 70]

 Hello my pd frnds...

I'm learning JavaScript and i've tried solving this geometric progression without success. The first and last terms are given which are a and b respectively according to the image attached. d is the common ratio and n which is the number of terms is not given. My solution prints way more than expected, my answer shouldn't be anywhere over the last term. This example should terminate at 27 . thereby adding only 3 items to the array.

Solution attached as image

If he's not finding the answer himself he learned nothing.

TIP: Cut the code in pieces, write down what the code does in every line. This can help you.

@Bitcoinani Any luck? If you'd like some clues, I think I can nudge you in the right direction. Let me know if you've gotten any closer to a working solution.

Hahaha, I'm not the only one who knows JavaScript here, you know. =P So, I'll start you off with some leading questions. Look through your code and see if you can find the problem I'm pointing at with them:

1. Right now, you have a for loop nested inside a do-while loop. Your while condition is what checks whether you've reached the required term - when is it checked right now? How could you rearrange your code so it could be checked at a different time (possibly earlier)? Do you really need two loops?

Oh i understood now... so what if i do it with a single while loop?

I think you'd have a much easier time arranging your logic - that's the way I solved the problem!

oh okay sir, wait i m doing it..

OMG serlite sir I solved it thank you so muchhh...

 

function gp(a,b) { 

       var arr = [];

       var d = 3;

       while (a<b){

       arr.push(a); a = a*d;

       }

   console.log(arr);

}

 

Thank you your presence solved my problem

Well done! Glad you were able to get the solution in the end.

Good luck on your continued learning of JavaScript!
