arr2 = [3,0,7,1,2,4];
Code (JavaScript):
I wish to create a new array using the values on arr2 as the indexes on arr1.
For example arr1[arr2[0]] would be 140 and so on.

Final output of the new array would [140,201,731,188,123,172];

For a small amount of numbers I could use push but arr1 and arr2 could potentially have a lot of numbers....

i have this problem. Is there a way i can create this using javascript loop and array.

View attachment 270390

as you can see, when i input 19,433.33 it will be subtracted by 1,766.67, then the difference will be displayed to the right which is 17,666.67, then subtracted again by 1,766.67. it will just do this until it reaches 0.00

Can you enlighten me on how this will work using array and loop in javascript?

In my mind I would like the user experience to be as simple as possible; focused on the centre of the screen, on a single drop down menu, of which when a choice is selected that menu visually slides out of the way (so the user doesn't feel disoriented), as a new one slides in, and so forth, until the selections are exhausted.

What should I look into to achieve this please ?]]> 3
