Show HN: Small TypeScript library to work with quadkeys in a fast way (github.com)

I am developing a website called Geocode Map Viewer(https://tools.9revolution9.com/geo/geocode/). I was looking for a suitable TypeScript library to visualize Quadkeys on the map, but unfortunately I couldn't find one. So I decided to develop my own library, using the sample code available on the Microsoft Tile Maps page as a reference.
