isFirstSelection

function LSM.isFirstSelection<T>(lsm: LSM<T>, selectable: T): boolean;

Returns true if the item is the first in the selection order.

The selection order reflects the order in which items were selected, not their position in the selectables array.

Example

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

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

LSM.isFirstSelection(lsm, "b"); // true
LSM.isFirstSelection(lsm, "a"); // false
