Bratus

A tree-shakeable library of automatically curried, data-last utility functions.

This is a very early version and more functions will be added.

So far the functions available are: add, compose, curry, filter, head, map, reduce, tail.

The arguments are generally the same as lodash/fp and Ramda but I'll probably do some proper documentation at some point. If not you can look at the source for now.

Install

npm:

npm install --save bratus

yarn:

yarn add bratus

Some examples of using the module:

// ES5 (pre Node v4) 
var bratus = require('bratus');
bratus.add(1, 2);
bratus.head([1, 2, 3]);

// ES2015
import {add, head} from 'bratus';
add(1, 2);
head([1, 2, 3]);

If you use Webpack 2 or Rollup then a tree-shakeable version of the library with ES2015 modules is used so you only include what you use in your bundle.

Why

I was playing with existing libraries that do tree-shaking in Rollup and Webpack 2 and found that it didn't work as expected. Extra functions were included that were not being used. So I just started writing my own and found that compiling the tree-shaking build into a single file with named exports gave the best results.

I just kept on going and then started measuring the results and found I was able to make some functions faster. You can run the benchmarks by cloning the repo then doing the following:

yarn
yarn benchmark
