hello im a beginner coder,currently i have an idea for my company (non coded related) where i can take pictures of aparament maps and store gate codes. What should i learn so i can make a website save images and be able to read the buildings numbers and generate a pathway to it or a simple star, that way i can locate a unit/aparement faster, also storing gate codes since our Work Orders dont always have gate codes, we either have to look for one or wait until someone lets us in. i know simple html and css, currently trying to understand javascript
