Singletons and the static keyword (in class declarations), that took me a while. I had a hard time with it when I developed in PHP. Interestingly, when I started doing more work in JS I got the concept :)

 

In which cases do you use singletons? I’m not big fan of them and try to use it as little as possible.

 

It's useful to store global state. Similar to Vue's vuex or React's redux.
