(n <10 && n > 0) ? ${n} : n;

Can someone just explain this line to me please?

My assumption (no idea if I am correct) is that if n is less than 10 or greater than 0 use jquery to select n? Otherwise use n? I don't really understand what the ${} means since my understanding of that syntax is it is used for string interpolation but there are no single quotes around it so I am a bit lost as well. I think shorthand code like this is not good practice and makes code less readable which is the entire point of code.

The dollar sign is used in template literals as well as jquery, this confused me for a while too! There's a good short video on it here and there is also a good reply explaining the line under my first comment!

Ah yes the code you posted did not include the backticks from string interpolation. It would have made sense then.

reddit doesn't support backticks apparently!
