There's a wiki page that explains this with lots of examples in different programming languages: https://wiki.openstreetmap.org/wiki/Slippy_map_tilenames

If you're using an existing Javascript library to display map tiles, then it may already contain functions that save you a bit of work, such as these in Leaflet.
