This module provides a list data structure, which can be used instead of an array. A list is more computationally expensive than a regular array, but contains various methods and properties, which make manipulating list data simple, chainable, and readable.

Examples

Example 1

import { List } from "@exts/list";

const myList = new List(10, 20, 30, 40);
myList.push(50);
console.log(myList.last) // 50
console.log(myList.indexOfLast) // 4

// explicit return typing is necessary for some methods
// because TypeScript cannot infer the type of `item` from the type of `item.value`
myList.find((item): item is Item<number> => item.value > 10)!.value // 20
myList.find((item): item is Item<number> => item.value > 10)!.index // 1

// skip the first found item
myList.find((item): item is Item<number> => item.value > 10, 1)!.value // 30

myList.fromUntil(item => item.value === 10, item => item.value === 30)
 .values // [10, 20, 30]
