@barandis/utils
This is simply a library of small dependency-free utility functions. It's meant as a place for me to keep things for my own personal use, but if there's anything you find here that you'd like to use, please feel free (in accordance with the MIT License, of course).
I'm not planning on providing any documentation short of what's on this page, but there are extensive doc comments, and the unit tests probably provide the best documentation of all.
Installation
If you want to install the package, get it from npm.
npm install --save @barandis/utils
Once you do, you can import
or require
directly from @barandis/utils
as normal.
// import syntax
import * as utils from '@barandis/utils'
// require syntax
const utils = require('@barandis/utils')
Alternately, you can import individual modules by adding '/modules/<module-name>'
to the end of the package name. For example, if you only want to use a function out of the iterators
module, you can do this:
// import syntax
import * as iterators from '@barandis/utils/modules/iterators'
// require syntax
const iterators = require('@barandis/utils/modules/iterators')
The module to which each utility belongs is listed in the table of utilities below.
