The world of JST connectors, JST stands for Japan Solderless Terminal, that’s pretty much more than what you really need to know in my opinion other than the technicals. If you’re like me and only interested because you find yourself needing to replace a broken connector, well what I’ve rapidly figured out is you need to make sure you’re getting the correct size (duh), there’s obviously the basic questions you would know, such as how many pins, but they come in different sizes. 1mm, 1.25mm, 1.5mm, etc.
Your best bet is to actually measure your connector and look for an exact match. This page was a good starter on how to distinguish what you’re looking for.

Then you either go to genuine sellers or you simply find what you’re looking for on eBay. You could go to Aliexpress, if you’re ok with waiting a very long time.
