Interactive Pricing

Hi! I'm posting my first challenge here.

I am adding the first version now as I can see some items need to be changed to make them work better. I am aware that it can be created better. I think about js that maybe it would be better to use arrays rather than "ifs" as a solution for sliders. What do you think? I am curious about your opinion on what could be created in a more correct way. What solutions can I improve to make it more professional.

This was the first time I used sliders with an input style "range", so I had to learn it from the tutorials.

I am looking for your advice and feedback.
