@onelinecode/onelinecode

Awesome javascript in one line of code

A collection of utilities and helpers following the principle: Keep it as simple as possible in one line of code.

As long as we area dealing with JavaScript, the library assumes that the user provides valid input. No type checking or other verifications of the arguments are part of the functions. The library tires to use the simplest and most performant code possible. To keep the functions as simple as possible they will be reduced to the core functionality: "one function should have one specific functionality only".

New functions will be added every time there is an article being published.

All functions are written in ESNext esmodules (./src) and available as -umd (./dist/index.js) with the onelinecode namespace (e.g. window.onlinecode) -commonjs (./dist/index.cjs.js) -esm (./dist/index.esm.js)

Available function

Array

isEmpty

Returns a boolean false if the array is not empty or a boolean true if the array is empty.

lowestNumber

Returns the lowest numerical item of the array.

removeDuplicates

Returns a copy of the array. Removes duplicate entries, keep in mind that it works only for entries with primitive values (string, number, bigint, boolean, undefined, symbol, and null). Preserves the order of the entries.

occurrenceMap

Returns an object where the keys are the array entries and the values the number of their occurrences.

Installation

$ npm install @oneliner

$ yarn add @oneliner

Usage

For example, you want to shallowClone an array:

import { shallowClone } from '@oneliner/array';
let array = [1];
let arrayClone = shallowClone(array);

Testing

The library has 100% code coverage with ava and passes the build on (travis-ci.com)]|
