import { LSM } from "@monstermann/lsm";

let lsm = LSM.create(["a", "b", "c"]);

lsm = LSM.goToPrev(lsm);
lsm.selected; // ["c"]

lsm = LSM.goToPrev(lsm);
lsm.selected; // ["b"]

lsm = LSM.goToPrev(lsm);
lsm.selected; // ["a"]

lsm = LSM.goToPrev(lsm);
lsm.selected; // ["a"] (no change, at start)

lsm = LSM.goToPrev(lsm, { loopAround: true });
lsm.selected; // ["c"]
