How to make a similar calculation calculator?

Question

JavaScript

There is a good calculation calculator with a slider: http://pobeda-63.rf/ (scroll a little to the "Percentage Calculator").

How difficult is it to make one?

My brain is boiling over something, I can’t even properly formulate a request to Google to find similar solutions ...

Answer 1

Here is the slider in use: https://github.com/IonDen/ion.rangeSlider/blob/mas...
Connect and configure it first. And then, I think, with the help of JS, you can somehow display the values ​​​​in other blocks on the page (as in the right side of the calculator from the site that you threw off).
In general, nothing complicated, but take the time to figure everything out.
