prepend

function Dll.prepend(dll: Dll<T>, value: T): DllLink<T>

Adds a value to the beginning of the doubly-linked list. Returns the link node, which can be used with unlink for later removal.

Example

import { Dll } from "@monstermann/dll";

const dll = Dll.create<number>();
Dll.prepend(dll, 1);
Dll.prepend(dll, 0);
// List is now: [0, 1]

// The returned link can be used to unlink later
const link = Dll.prepend(dll, -1);
Dll.unlink(link);
// List is now: [0, 1]
