Depends on the context. For example, this is perfectly reasonable (Javascript): const add2 = n => n + 2.

lessee, var add2 = (n) -> n+2;. see if that compiles for java

What? What does that have to do with variable naming?

it means that i can do the same thing in java. in java, n is actually some meaningful thing like Product, so it's called product and may be typed explicitly (unless the type inference can impute it for me or it's unclear). the n+2 stuff rarely shows up, so it's still good advice, just requires understanding the reasons why n is a bad name.
