Installation

You can install the List Library using npm or yarn by executing the following command:

npm install @js-ninja/list

or

yarn add @js-ninja/list

Usage

To use the library, you need to import the List class. Here's an example import statement:

import List from "list-library";

The each method

The each method allows you to efficiently iterate over an array or a DOM collection. It takes the following parameters:

• arr - an array, NodeList, or HTMLCollection to iterate over.
• cb - a function that is called for each element. It takes the following parameters:
  • item - the list item.
  • index - the index of the item.
  • arr - the list.
• breakOn (optional) - the index at which the function will stop execution.

Example usage of the each method:

const arr = [1, 2, 3, 4, 5];

List.each(arr, (item, index) => {
    console.log(item); // Outputs each element of the array
});

The filter method

The filter method allows you to efficiently filter an array or a DOM collection. It takes the following parameters:

• arr - an array, NodeList, or HTMLCollection to filter.
• cb - a function that is called for each element. It takes the following parameters:
  • item - the list item.
  • index - the index of the item.
  • arr - the list.
• Returns the filtered array.

Example usage of the filter method:

const arr = [1, 2, 3, 4, 5];

const filtered = List.filter(arr, (item) => item % 2 === 0);

console.log(filtered); // Outputs [2, 4]

The map method

The map method allows you to efficiently transform an array or a DOM collection. It takes the following parameters:

• arr - an array, NodeList, or HTMLCollection to transform.
• cb - a transformation function for each element. It takes the following parameters:
  • item - the item from the original list.
  • index - the index of the item.
  • array - the original list.
• Returns the resulting array.

Example usage of the map method:

const arr = [1, 2, 3, 4, 5];

const doubled = List.map(arr, (item) => item * 2);

console.log(doubled); // Outputs [2, 4, 6, 8, 10]
