Chek NPM | npm.io

What is Chek? Well we have a guy we call Chekov, as in "I can do zat Captain I can do zat". So we shortened it to "Chek". Hey there's a logger named after "Winston" right.

Anyway Chek is a slimmed down lib for common tasks like check if "is" a type or convert to a type. There are helpers for dealing with strings, converting objects to arrays and back (handy for Firebase type apis) and so on.

Nothing special just a nice little toolkit preventing the need for large libs like Lodash or Underscore (both great of course).

The end game is simple. Have about 90% or so coverage for common tasks preventing the need for a larger footprint.

Comes with 100% test coverage out of the gate. Some handy methods like push, splice, shift, unshfit and so on that handle immutability as well as other methods where applicable.

Installation

npm install chek -s

Usage

Using Typescript

import * as ck from 'chek'; // or import { isString, slugify } from 'chek';

let slug = 'i can Do zAT';
if (ck.isString(slug))
  slug = ck.slugify(slug) // result: 'i-can-do-zat';

Using ES5

const ck = require('chek');

// same as above.

array - things like contains, containsAny, duplicates.
from - things like fromEpoch, fromJSON, tryWrap & tryRequire.

Please Note the following tables are here for convenience you should ALWAYS reference the "docs" below for updated method signatues, there's only so much time in the day.
