Immutable Array.prototype.splice().

Install with npm:

npm install @immutable-array/splice

Usage

Same API with Array.prototype.splice().

/**
 * Removes elements from an array and, if necessary, inserts new elements in their place, returning the deleted elements.
 * @param array Base array.
 * @param start The zero-based location in the array from which to start removing elements.
 * @param deleteCount The number of elements to remove.
 * @param items Elements to insert into the array in place of the deleted elements.
 */
export declare function splice<T>(array: Array<T>, start?: number, deleteCount?: number, ...items: T[]): Array<T>;

Example

Delete all:

import { splice } from "@immutable-array/splice"
const originalArray = ["a", "b", "c", "d", "e"];
const resultArray = splice(originalArray, 0);
assert.deepStrictEqual(resultArray, []);

Delete range: 1-3

import { splice } from "@immutable-array/splice"
const originalArray = ["a", "b", "c", "d", "e"];
const resultArray = splice(originalArray, 1, 3);
assert.deepStrictEqual(resultArray, ["a", "e"]);

Delete and Insert = replace index 0 with "x"

import { splice } from "@immutable-array/splice"
const originalArray = ["a", "b", "c", "d", "e"];
const resultArray = splice(originalArray, 0, 1, "x");
assert.deepStrictEqual(resultArray, ["x", "b", "c", "d", "e"]);
