import type { NumericArray } from "@thi.ng/api";
/**
 * Fills given array with values in `[start,end)` interval from `index` and with
 * optional `step` size.
 *
 * @remarks
 * `start` and `end` default to 0 and array length, `step` defaults to 1 or -1
 * (depending on range). Returns array.
 *
 * @example
 * ```ts tangle:../export/fill-range.ts
 * import { fillRange } from "@thi.ng/arrays";
 *
 * console.log(
 *   fillRange(new Array(5))
 * );
 * // [ 0, 1, 2, 3, 4 ]
 *
 * console.log(
 *   fillRange(fillRange([], 0, 10, 20, 2), 5, 20, 8, -2)
 * );
 * // [ 10, 12, 14, 16, 18, 20, 18, 16, 14, 12, 10 ]
 * ```
 *
