uselib

JavaScript needs a standard library. We try to provide one that is functional and small.

Rationale

Wouldn't it be nice if JavaScript has a standard library that is well thoughtout and complete? You shouldn't need to write your own leftPad() function everytime you need it, but you shouldn't need to search for an npm package for each fundamental task you are trying to perform either.

I feel many utilities out there are too specialized, and do not fulfill the role of a standard library. uselib strives to be:

• functional in nature, modeled after Elixir and Clojure
• small in size
• compliant with ES6 modules
• comprehensive

Functional languages like Haskell and Elixir have given much thought to what a good standard library should be like. We strive to port the paradigm to JavaScript.

Usage

Foolproof way:

const { Enum, List } = require('uselib/require');

// the full power of standard library available to the rest of the code

ES6 way, which is much more efficient, but requires webpack tweaking:

import { Enum, List } from 'uselib';

// the full power of standard library available to the rest of the code

Program Size

uselib can make your transpiled code smaller:

• We try to be very small in size to begin with
• Using ES6 module allows tree shaking
• Proper webpack/rollup configuration allows uselib code to be included only once, even if it is used by many upstream dependencies

Modules

• Str
• List / Arr
• Obj
• Enum
• Stream
