Method resize

data_structures/unstable_2d_array.ts:214–250

* Resize the 2D array. * The origin for the resize is the top left corner, or rather the first element. * * @example Usage * ```ts * import { D2Array } from "@std/data-structures/unstable-2d-array"; * import { assertEquals } from "@std/assert"; * * const arr = new D2Array<boo

(width: number, height: number)

   * If larger than current height, the 2d array will add instances of {@linkcode D2Array.prototype.initialValue | `initialValue`} to fill up.
