Nit: what about

  return hasScanResults && isInfected ? "infected-icon" : "clean-icon";

(or even better, what about an aux function that will be reused by
getStatusIcon_?

[proberge, 2017/03/29 21:29:36]

Done. Simple enough to not need a helper function.

[ftirelo, 2017/03/29 20:59:11]

Same as above.

Done.
