javascript - if and or (||) statement

if (window.location.pathname == "/" || window.location.pathname == "/yyy.asp") {
  runSlideShow();
}
if (
  window.location.pathname == "zzzz.html" ||
  window.location.pathname == "/xxx.html"
) {
  runSlideShow();
}

How do I merge the if statements so there is only one {runSlideShow();} rather than two;

currently I cant seem to have more than two window.location.pathname statements with an || in between.
