anchor

function LSM.anchor<T>(lsm: LSM<T>): T | undefined;

Returns the most recently used anchor in the selection.

An anchor is the starting point of a selection range. When multiple anchors exist, this returns the one that was most recently added to the selection.

Returns undefined if there are no selections.

Example

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

const lsm = LSM.create(["a", "b", "c", "d", "e"]);

LSM.anchor(lsm); // undefined

const selected = LSM.goTo(lsm, "c");
LSM.anchor(selected); // "c"
