Description
Lightweight and without any external dependencies arare enables you to write tacit, point-free, declarative & clean code while avoiding side-effects and mutations. Internally the library itself, comprised of over 200 functions, follows the functional programming paradigm and is materialized using fundamental functional qualities such as currying, recursion, tail calls, high-order functions, referential transparency, side-effects elimination and function composition. Additionally, arare utilizes automatic variadic currying for its functions, thus allowing the user to write more flexible, practical & minimal code, compared to regular strict currying. Finally, the library comes with a build-in interactive REPL environment, useful for directly inspecting and experimenting with all available modules without leaving the console.
Please note that project is in its early days and that it is currently under active development.

Contents
Install
npm install arareUsage
Import arare and start using directly any of the available modules.
const A = require('arare')
A.map(A.add(10), A.range(1, 4, 1))
//=> [11, 12, 13]Alternatively, select and import only the modules that you need.
const {add, map, range} = require('arare')
map(add(10), range(1, 4, 1))
//=> [11, 12, 13]REPL
Initially, install arare globally in order to be able to access the REPL environment.
npm install -g arareTo launch the REPL simply type arare from anywhere in your console.
arare # launch REPLAPI
