the solution to this is

type Hiscores = Array<Hiscore>

[David-Else]

@bradzacher Cheers! Eslint did not like that, but likes type Hiscores = Hiscore[]; which seems even nicer and works fine :)
Out of interest, do you consider this issue a bug? It would be nice if it automatically suggested your solution.

I hadn't thought of providing a fixer for this.
We've had this issue raised a couple of times, so it's probably worth adding a fixer for this specific message - it's a pretty straightforward fix!

@bradzacher Are you still fine with adding a fixer for "noEmptyWithSuper" message? I'm gonna take it over and open PR.

[bradzacher]

Definitely, go for it!
This is a common issue that people have raised a few times, so a fixer for it would be ace.
