    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 functions


    See ./doc/


    $ npm i @onelinecode/onelinecode
    $ yarn add @onelinecode/onelinecode


    For example, you want to shallowClone an array:

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


    The library has 100% code coverage with ava and passes the build on Build status from travis-ci.
