@dizmo/functions-filter

Asynchronously filters an array of items: The Array.prototype.filter function does not allow to filter an array using asynchronous predicates. However by applying the filter function, it becomes possible to do so.

Usage

Installation

npm install @dizmo/functions-filter --save

Require

const { filter } = require('@dizmo/functions-filter');

Examples

import { filter } from "@dizmo/functions-filter";

const even_numbers = await filter([0,1,2,3,4], (n) => new Promise(
    (resolve) => setTimeout(() => resolve(n % 2 === 0))
));

const odd_numbers = await filter([0,1,2,3,4], (n) => new Promise(
    (resolve) => setTimeout(() => resolve(n % 2 === 1))
));
